What Is a Radon Resistant Home?

If your home was developed within the last ten to twenty years, it’s likely that the construction crew adhered to radon resistant standards. This includes the use of radon-resistant materials and procedures to mitigate the buildup of the deadly gas inside your radon resistant home.

In the commercial and professional world, this is referred to as Radon Resistant New Construction or RRNC, for short. Without any further context, you might hear this term and fall into the trap of thinking that newer homes cannot be affected by Radon. There are several reasons this is wrong, the most important of which is that RRNC doesn’t actually mean what you think it does.

The name implies that construction practices ensure a home resists radon. Naturally, you’d expect a newer home to be less of a risk. You might even ignore testing altogether. The sad truth is that every single home or building is susceptible to the deadly gas. Even those built specifically to RRNC standards, within the most recent decade.

What Does RRNC Actually Mean?

Modern Real Estate PropertyWhile the standards and practices are designed to mitigate radon and prevent it from entering a home, it’s more of a preparation process than it is actually securing a property. In most cases, RRNC simply involves the pre-installation of radon system pipes. The foundation is laid out, and if and when there is an issue discovered, the only step required of you is to install a mitigation fan.

This eliminates the need to later uproot the foundation and home to install a sub-slab mitigation pipe system. As it’s pre-installed, a crew can later come in, install the necessary fan and begin the exhaust process to mitigate the radon that has built up inside a home.

Technically, since there is no working fan, the home is only “radon-ready” not activated. Furthermore, as homes deteriorate over time, cracks, seams, and settling can cause natural seals to warp or wear. Radon seeps into a home generally through these cracks or gaps, rising most commonly from the soil underneath our feet and homes. So, even a home with RRNC measures can see radon build up inside, at lower levels, after a significant amount of time.

When radon builds up inside a home, there are no telltale signs. In fact, the only way to reveal its presence is to directly test for it. The gas is odorless, colorless, and tasteless. Damage is incurred over an extended period of time, and there are little to no symptoms of radon poisoning.

What this means, is that if you never have your home tested, you could be living with the deadly gas for years, none the wiser.

Are Radon-Resistant Homes Still at Risk?

The short answer is yes, all homes and properties are at risk for radon buildup. Even homes that have an active radon mitigation system and constantly running fan, can still be plagued by elevated radon levels within. This can be caused by poor ventilation, a malfunctioning system, or even the increased presence of the gas.

Certain types of rock – such as karst – are more likely to give off harmful radon. Even granite can release radon, which means yes, your granite countertops can be a source, though the levels are generally so low as to not be dangerous.

Since these types of rock are abundant pretty much everywhere, it means that no single location or region is safe. It also means that when these types of rocks or conditions are more common, the risks of higher radon levels are also increased.

One common misconception passed around, if a home nearby is tested and found safe, yours will be too. This is dead wrong, as even your closest neighbor can have varying levels. It depends more on the condition of your property, the makeup of soil and resources beneath your feet, and even the size or layout of your home.

In short, it means that you should always test your home regardless of age, location, and or radon levels in your area. It is entirely possible to live in a subdivision or on a street, where your home is the only one plagued by elevated radon levels; just as the opposite can be true. And since testing is the only way to discover its presence, that’s what you should do.

To add to this, many believe that radon is only an issue in north and western parts of the country (US) because most homes in those regions have basements. This is completely false. Radon can build up even inside a home without a basement, and it’s not confined to a single country or region. In fact, both Canada and the UK have similar radon measures as the US. Other countries can see elevated radon levels, as well.

How Often Should You Test for Radon?

old abandoned homeMost experts recommend testing your home for Radon once a year or so. We, however, recommend testing your home at least twice a year. The best times to do so are during the warm and cold months because this is usually when all egress to your home are sealed and remain so – usually, you don’t want the cold to enter, or the A/C to escape in the heat. Due to weather, living conditions, and geography it’s entirely possible for radon levels inside a home to fluctuate. This means, that you could test your home in the fall or winter, and find different levels as you do in the summer.

Testing multiple times is the best way to be sure your home is not affected. Furthermore, there are different types of tests, including short and long-term. Short-term tests will only tell you the current levels inside the home over a smaller, bite-sized period. Long-term gives a much clearer picture of the average radon levels in your home year-round.

If you need more information on testing your home, there’s plenty here at Radon Resources. The best place to start is with a short-term test, and if you discover elevated levels – or close to it – then you should do a long-term test to find the average levels in your home.

It is important that you test as soon as possible because it’s an extensive, drawn-out process. That doesn’t mean it’s difficult or time-consuming so don’t shy away. You simply leave samples vials untouched for a specified period of time and then mail them to a remote lab.

However, it takes some time because the vials have to be left out to collect air samples. Then they have to be mailed to a lab, tested, and the results need to be mailed back or posted online. All of this takes some time to happen, so you won’t get your test results back overnight. That means, if you do have elevated radon levels in your home, you’ll be living with them for some time before you can remedy the issue.

Again, that is exactly why we recommend testing your home as soon as possible. The dangers of radon are very real, despite many believing it is a hoax, and or a made up concept. Unfortunately, that is not the case. At any rate, wouldn’t you agree it’s better to be safe than sorry especially when your family is concerned?

The Airthings Wave is a Bluetooth-Enabled Radon Sensor

Every year at CES a variety of new electronics and gadgets are unveiled. Not all of the devices are made available on store shelves because some are just for show.

CES 2017 kicked off late last week, and it was much of the same.

But Norway-based Airthings – previously known as Corentium – showed off their new device, an active radon sensor, and it will soon be available for all.

You may be wondering why this is important, so consider this. Annual deaths from radon gas are higher than drunk driving, which is responsible for more than 17,000 deaths a year as opposed to 21,000.

Introducing the Airthings’ Wave

The Airthings Wave is a Bluetooth enable radon detector for homeowners. It is so named because once installed you can simply wave your hand in front of the sensor to see a reading of the radon levels in your home.

Airthings Wave Radon SensorA color-coded LED ring on the front of the Wave will turn different colors to indicate whether the radon levels are safe or dangerous. Green means the levels in your home are normal – and safe – while yellow is a warning, and red means dangerous. The idea is that if the sensor shows yellow or red, you will take action by further testing your home.

The Wave also has temperature and humidity sensors to detect other changes in the home.

All data is synced to a mobile app – available for both Android and iOS – and organized appropriately. After some time of operation, you will be able to see the long and short term radon averages for the levels in your home.

They plan to sell the device for $199 and will begin shipping in March of this year.

If you want an active radon detector in your home, this is a great option. Since, radon gas is responsible for more than 21,000 lung cancer deaths each year, second only to smoking, you should check your home at least once.

If you’re not willing to purchase a long-term sensor such as the Airthings Wave, then you should have your home tested at least once per yer – though we recommend doing so twice per year.


If you’d like to read more about the Airthings Wave, you can do so on the official product page here.


Learn About Radon Gas from the Pros

Here at we’re big on raising awareness about the dangers of radon gas. You’d be surprised how many people don’t know it is hazardous.

Did you know that it could be collecting inside your home this very moment?

We thought this was a good time to enlist some help, so we reached out to several folks to get their opinion on the topic. These contacts are experts on radon, and have considerable experience in the field.

Radon Is the Second Leading Cause of Lung Cancer In Non Smokers

According to the United States Environmental Protection agency radon gas is the second leading cause of lung cancer in non smokers. It is responsible for more than 21,000 deaths each year due to radon-induced cancer.

Lung cancer is more commonly associated with smoking and tobacco products, among other things. Many people believe that if they don’t smoke a day in their life they are safe from lung cancer, but that’s not true. You can get it even if you don’t smoke. All it takes is exposure to elevated levels of radon gas inside a residence or building.

“About 2,900 [radon-related] deaths occur among people who have never smoked.”

You can be exposed to the deadly gas in your home, schools, daycares, public buildings – like libraries – or even your place of work.

In January 2005, Dr. Richard H. Carmona – the United States Surgeon General at the time – issued a national health advisory on radon. You can read that here.

In that report was the following information:

The Surgeon General’s Workshop on Healthy Indoor Environment is bringing together the best scientific minds in the nation to discuss the continuing problem of unhealthful buildings. Indoor environments are structures including workplaces, schools, offices, houses and apartment buildings, and vehicles. According to a recent study, Americans spend between 85 and 95 percent of their time indoors.

In just the past 25 years, the percentage of health evaluations that the National Institute for Occupational Safety and Health at the Centers for Disease Control and Prevention (CDC) has conducted related to indoor-air quality has increased from 0.5 percent of all evaluations in 1978, to 52 percent of all evaluations since 1990. This means that in those years, the evaluations related to air quality concerns have increased from one of every 200 evaluations to one of every two.

The problem is also adversely affecting our children’s health as millions of homes and apartments and one in five schools in America have indoor air quality problems. This can trigger various allergies and asthma. Asthma alone accounts for 14 million missed school days each year. The rate of asthma in young children has risen by 160 percent in the past 15 years, and today one out of every 13 school-age children has asthma. Dr. Carmona is especially focusing on how unhealthy indoor environment affects children, as he promotes 2005 as The Year of the Healthy Child.

So, we’ve established radon is a problem. But how do you identify it? Can you prevent it or get rid of it?

Radon Testing Is Key

Radon is difficult to detect. In fact, the only way to discover its presence in your home, office, or residence is to test for it specifically. You can either do this yourself with the appropriate testing equipment, or you can hire a professional.

“Normally, radon gas disperses harmlessly into the air; but, it can get into homes, particularly homes with basements and since you can’t see it or smell it, you can’t tell if it is there unless you test for it.” – Mike Chamberlain of MC2 Inspections.

As Mike says, testing is the only way to tell whether or not radon is in your home. But just what is radon?

“Radon is a ‘noble’ or ‘inert’ gas, which means it doesn’t combine readily with other elements. Radon is the heaviest known gas, 9 times denser than air, and it consists of one, tiny, single atom, so it can penetrate most common building materials like sheet rock, mortar, wood, most insulation, even concrete, block walls and or flooring.”

radon gas disclosure recommends testing a homeThe invisible gas can seep into your home, where it collects in greater amounts. Since it doesn’t have an odor, there’s no way to tell if you’re living in a dangerous environment or not, at least not without testing.

“Testing is the only way to find out about your home’s radon level. The EPA and the Surgeon General recommend testing of all homes below the third floor for radon.”

The reason why they recommend testing the lowest livable space – including basements – is because radon is dense. Once it seeps into a home, it commonly builds up on the lowest level. This means that parts of your home may not have dangerous levels, while others do. It also means that every home is different.

Radon can seep into any type of home, even those without a basement. Furthermore, it will affect every home differently. It also means that even if your neighbor’s home is safe, that doesn’t mean yours is and vice versa.

Testing your home for radon is key.

How Much Radon Is Too Much?

In the United States, the recommended action limit of radon gas in a residence or building is 4.0 pCi/L. If a radon test shows levels at or exceeding that number, you absolutely need to contact a professional and have a radon mitigation system installed.

A mitigation system will ventilate the radon gas and remove it – at least in concentrated amounts.

According to the United States National Safety Council “no level of radon exposure is considered safe.”

Radon Testing kitRadon is hazardous, period. It doesn’t matter what the limit is, you want to alleviate exposure to the gas as much as possible, and that’s true of any building or residence where you spend a majority of your time.

While we recommend taking action for levels at 2.0 pCi/L or higher, 4.0 is considered to be the danger zone.

Would you like to know what “pCi/L” means? The National Safety Council also has the answer for that.

“A pCI – or picocurie – is a measure of the rate of radioactive decay of radon gas (the tiny particles that can get trapped in your lungs when you breathe).”

It’s a standard unit of measurement for radiation, and since radon is a natural radioactive gas, that’s how it is measured too.

Radon Can Be a Problem In Schools, Daycares, and Nurseries

Homes, apartment buildings, and condos aren’t the only places that can be affected by radon. The gas can seep into any building, including public ones. That means schools, day care centers, work and office buildings, industrial properties and much more.

Old SchoolhouseBut since radon causes the most damage over a long-term period, it’s our children we should be worried about.

Laura Rossinow, a Boston realtor that is also an NRPP Radon measurement provider, believes that there should be laws in place to protect our children and educators.

“Children are raised in homes that have never been tested for radon and they go to schools that have never been tested for radon. Long term exposure is the highest risk! Protect your family…test for radon gas today!”

Sadly – and we did talk about this recently – there aren’t many laws that require schools or day care centers to take action. Most that do exist call for testing a property, but that’s it.

Did you know that an estimated 70,000 US classrooms have high, short-term radon levels? Think of how many children spend time in those classrooms exposed to radon. It’s time to start taking this matter seriously.

Everyone Should Know About Radon

There are so many alarming statistics and facts related to radon. For instance, did you know radon is the second leading cause of lung cancer in the US? It’s the leading cause in non-smokers.

What about the fact that there are more than 21,000 deaths each year from radon-induced lung cancer? Or, it’s estimated that every one-in-fifteen homes in the US has elevated radon levels within?

Elevated radon gas levels across the countryYou can find all of these stats – and more – listed on the official US Environmental Protection Agency’s website.

If you don’t know much about radon or the associated dangers, then it’s time you become acquainted.

Chris Kristiansen from AirThings (previously Corentium) explains how Radon levels are affected by the changing seasons.

“Radon levels rise and fall with the seasons, with changes in your home’s ventilation, or changes in the ground around your home. That is why we recommend getting a digital radon detector that shows both short-term and long-term changes to the radon level in your home.”

Ultimately, just because you test earlier in the year and find lower levels doesn’t mean you are in the clear. Radon detectors allow you to constantly monitor the levels in your home, as Chris has successfully explained.

Regular tests of the environment where you spend your time is recommended. So, you should be testing your home more than once per year, but at least once if you want to keep things minimal.

Companies like Airthings also offer a radon detector – similar to a smoke or carbon monoxide detector – which can be used to identify regular levels in your home. This is not out of the question, especially if you live in an area that is more susceptible to radon gas.

Can I Still Sell My Home with High Radon Levels?

Can I sell my home with high radon?

Preparing your home – one you lived in for years – so it’s presentable to strangers is frustrating. Come to find out, you have to pay for a slew of updates if you want your listing agent to consider putting it on the market.

The outside of your house needs paint. A bathroom needs to be cleaned and remodeled, and your kitchen needs to be updated – with new countertops and appliances no less. By the time you’re done with all that, there’s no reason to leave! The whole house will be like new!

To make matters worse, you just had your home tested and found out there are high radon levels inside.

On top of these adjustments, it doesn’t make sense to pay even more for testing and mitigation. But how will you ever sell the home with those elevated levels? It’s not like you can hide that information from a potential buyer, right?

Radon Testing and Real Estate Transactions

During real estate transactions, radon testing can be a headache, especially if you discover high levels. It becomes an even bigger problem as more people learn of radon and its dangers.

Radon in Real estateAfter all, radon is odorless, colorless, and tasteless. The fact it’s invisible to the naked eye and undetectable – without a proprietary test – means most people would overlook it.

But as much of a hassle as it can be, testing for radon is important. Ensuring radon levels are acceptable – below 4.0 pCi/L – means you are securing the health of your family and anyone else that lives in your home.

If you knew for sure your home was dangerous, would you pass it on to another family without saying anything? If your answer is no, then you should have your home tested, at the very least.

Many people believe radon testing and mitigation are expensive, but they actually are not. To be honest, no one wants to pay money to remedy a problem in a house they will no longer live in, but it’s still necessary.

You can test your home for $30 or less by picking up a radon testing kit at your local hardware store or online. If you find elevated levels, you can hire a radon professional to retest – likely for free as a consultation – before mitigation.



Mitigation isn’t that expensive either. It can cost anywhere from $1,000 to $5,000 for the most expensive improvements. Services tend to be on the cheaper side of that spectrum.

When you consider the costs of lung cancer – which radon can cause – those numbers seem even cheaper.

Can I Sell My Home with High Radon Levels or Not?

There are no laws that prevent you from selling a home with elevated radon, so you can do it. But, in certain states there are laws that require sellers to provide a radon disclosure in real estate documents. In some, the disclosure must also include known testing results and maintenance data for a mitigation system.

We won’t discuss the ethics of selling a home with high radon, that’s for you to decide. Just know, it is possible and there’s nothing legally stopping you.

Do we recommend doing so? No.

Can I Sell My Home with High Radon If the Issues are Resolved?

Yes, and there’s nothing wrong with doing so provided you inform the buyer about the mitigation system in your home. It may not seem like it, but homes are more appealing when they have resolved issues – like high radon.

Image by SWAT Environmental

It’s natural to worry a potential buyer will walk away because of a mitigation system in the home, but educated buyers know better.

A mitigation system – when properly maintained – will keep the air quality in a home safe and clean from radon. So there is no immediate threat whatsoever.

And it’s better if you have the testing results handy and take action before a potential buyer identifies a problem. If radon is discovered before a transaction is complete, it can put negotiations on hold for weeks, maybe even months.

Plus, every day you are there is another you and your family are exposed to the deadly gas, unless you are not living in the house.

Buyers Can Request the Seller Handle Radon Problems

During negotiations, the buyer can request the seller take care of any radon problems, including testing and mitigation. It would be more advantageous to have these things taken care of before you get to that point. There’s no telling how long the delay will be if you have to wait for test, then have a mitigation system installed.

So, can I sell my home with high radon inside? The bottom line is yes, but you shouldn’t. Do with that information what you will.

State Radon Laws featured

Are There State Radon Laws That Require Radon Testing and Mitigation?

You’d think since Radon is the second leading cause of lung cancer in the US, there would be a lot of legislation surrounding the issue. It is the cause of more than 21,000 deaths each year, after all.

Sadly, that’s not the case. There aren’t many state radon laws that encourage testing or mitigation.

Elevated radon gas levels across the countryIn the late 80’s and 90’s, there was a big push in state legislature. Radon was a hot issue and it was covered by many. Attention and awareness have since died down, and laws related to radon have also fallen by the wayside.

About 75% of the 50 US states do have some kind of law that addresses radon gas, but not in the way you might think. For example, most laws require radon professionals to be nationally certified or licensed. Also, there are laws that require home sellers and realtors to disclose any known radon information about a property.

No state radon laws, however, require homes be tested for radon during a real estate transaction. That is concerning, to say the least.

We’re going to take a look at some of the state radon laws that exist and what they entail.

Radon Disclosure Laws

About 30-40 states have radon disclosure laws. What this requires is simple. During a real estate transaction, the seller must disclose any and all known radon levels or testing results.

Radon in Real estateIf they have never tested the property for the presence of radon, then that’s all they have to say during a home sale. This leaves the testing and mitigation on the shoulders of the buyer.

A small list of states also requires sellers to include a warning about the presence of radon in the home. This is generally included in the sale contract or an amendment to the sale documents.

The states that require a warning include:

  • AK
  • AZ
  • DE
  • FL
  • IL
  • KS
  • MD
  • ME
  • MI
  • MN
  • MT
  • NC
  • NH
  • NY
  • OH
  • OR
  • RI
  • SC
  • SD
  • TN
  • TX
  • WA
  • WI

Radon Certification Laws

Radon certification laws address the businesses and professionals that will be dealing with radon gas in homes. This includes companies that provide testing and mitigation services.

Complete Construction Safety20 to 30 states have laws in place that require professionals to earn a certification or license before they can practice radon duties.

The regulations outline procedures and requirements for qualifications, testing and mitigation standards, reporting and analytics, and finally penalties (for not following regulations).

There are also third-party certification programs like the NEHA that work directly with state governments to license and qualify professionals.

What this means for home and property owners is that you should always ask for qualifications when hiring a radon professional.

Radon Testing Laws

The first thing you should understand is that there are currently no national or state radon laws that require testing in homes. This means that sellers and property owners are under no legal obligations to have a residential building tested for the presence of radon.

A handful of states do require that schools and child care centers be tested.

States that require radon testing in schools:

  • CO
  • CT
  • FL
  • VA


States that require radon testing in child care centers (daycare and after school programs):

  • CT
  • FL
  • IA
  • NJ
  • RI


It is important to note that although these state radon laws require testing, that does not mean they also require mitigation to deal with elevated levels. This may seem counterintuitive to why these laws exist – and it is – but unfortunately, there’s nothing that requires a lot of these properties to mitigate the issue.

Currently, Rhode Island is the only state that requires radon testing for “public or high priority buildings” also. This includes places like the state courthouse, libraries, and similar public properties.

Maine does require that residential buildings be tested for the presence of radon every ten years after they are built, unless they have a mitigation system installed. Yet, to have the property tested a tenant or landlord must request it.

Radon Mitigation Laws

The following states require radon testing and mitigation if elevated levels are discovered:

Mitigation in Schools:

  • WV
  • RI


Mitigation in Child Care Centers:

  • ID
  • MD
  • MI


Mitigation in State Buildings:

  • NH

Radon-Resistant New Construction

Finally, we have the radon-resistant new construction state radon laws. These require that new homes and buildings be constructed using radon-resistant materials and techniques. In theory, these locations should not experience radon issues, but it’s still a good idea to test them regularly just to be sure.

The states that have these laws in place include:


  • CT
  • NJ
  • RI



  • NJ
  • MI
  • WA
  • MN

Help Raise Awareness

Now you see why we’re always talking about raising awareness for the dangers of radon. Most of the state radon laws are necessary, but still lacking. It would be great to see some of these states pass laws that also require property owners and sellers take action.

Radon and Real Estate Featured

Part Two: What’s the Deal with Radon, Real Estate, and Lung Cancer?

Continuing on from our previous article on radon gas and real estate transactions, we’re going to take a look at several more questions that have cropped up.

If you haven’t already, please read the previous article – especially if you’re active in the real estate market.

Let’s get right to it.

Can Indoor Plants Remove Radon from the Air?

Radon is what’s referred to as a “noble gas” which means it doesn’t react chemically with substances. In addition, it is relatively dense – despite being in gas form. The long and short is that this means no, plants cannot remove radon gas from the air.

Indoor plants near large bay window overlooking cityscapeNow, there are plants that can improve indoor air quality but that’s a different matter entirely.

Furthermore, if you have elevated radon inside your home you have a bigger problem. It means there’s an abundant source of thorium or uranium nearby – likely under the foundation of your home. Even if plants did help alleviate the concentration of radon, it wouldn’t matter because more would seep into your home.

The best thing to do if elevated radon is discovered is to have a mitigation system installed.

What’s the Deal with Radon Health Mines? Do They Really Cure Diseases?

No, they are nothing more than a placebo. There is absolutely no science to prove radon health mines can cure diseases, let alone that they are good for you.

Free Enterprise Radon Health Mine in MTRadon is the leading cause of lung cancer in non-smokers, second leading for everyone. And this generally includes the radon contained within homes.

The radon levels inside a health mine are much higher than the recommended levels as set by the EPA. Which means those who spend a significant amount of time inside these mines are damaging their bodies more.

Radon progenies emit alpha particles that cause severe tissue damage, which is how it causes lung cancer. These particles are inhaled and make it into the lungs where they stick to the inner lining. Even within your body, they continue to undergo radioactive decay turning cells cancerous.

What Geological Features Predispose an Area to Elevated Radon?

There are certain geographical areas that are more prone to elevated radon, but that doesn’t mean it can’t exist elsewhere. In the United States, instances of elevated radon gas have been reported in every state. Certain lands characteristics, such as Karst, require continuous testing because the underlying landforms dissolve over time and may change the levels of radon in your home.

Elevated radon gas levels across the countryRadon is emitted from uranium and thorium, which can reside in the soil and certain rocks underground. Because it is a dense gas, it seeps up from the ground and permeates surrounding areas on the surface. This is how it seeps into homes and collects in abundance.

High granite concentration can also contribute to elevated radon levels. There are some reports that limestone – found in states such as Florida – can be a contributing factor, as well. Sadly, there’s not enough evidence or proof to say for certain.

Is Radon the Only Dangerous Indoor Air Pollutant?

Radon is one of the most dangerous, yes, but it is not the only one. There are other pollutants such as ozone, nitrogen oxides, sulfur dioxide, lead, and much more.

The list of potential pollutants is extensive and sadly, many of them are not rare. It’s likely your home is plagued by at least one of these pollutants to which you are being exposed this very moment.

What makes matters even worse is that there’s no universal test to get the expansive scope of pollutants. You need to test for each individual problem. For instance, radon testing will give you an idea of the average radon levels inside your home. But that’s it, the testing kits will not reveal other pollutants in the air.

How Do You Check a Home You’re Buying/Selling for Air Pollutants?

For the most part, you don’t have to worry about most of the issues. A decent home inspection will reveal anything wrong with the home in question. This includes mold, asbestos, lead, and more.

As for radon, you can conduct a simple short term test. You may also be able to request previous testing results from the seller – if they have tested the home before.

Do All Old Houses Have Problems? Is a Guarantee?

No. There are many factors that contribute to problems in a home.

Image by Yale Rosen

Image of Lung Cancer by Yale Rosen

When trying to find asbestos or lead paint, for example, you factor in the year the home was built because developers change materials over time. The construction year may reveal whether or not builders at the time were using poor materials. It has nothing to do with the age of the house.

Mold and radon get worse as time goes on – so older homes will be more dangerous if affected – but these things do not happen simply because the home is old. Mold comes from moisture that has seeped into the home, and radon comes from a radioactive gas that enters the home through cracks in the foundation.

Just because the home you’re interested in is old, doesn’t necessarily mean you will encounter problems. The opposite is true of new homes. Just because a home is new doesn’t mean the home will be without them.

Also, levels vary from home to home even in the same neighborhood, or on the same street. Just because your next door neighbor tested their home and found elevated levels of radon, doesn’t mean you will. That’s why it’s always recommended that you test your home – or the home you’re buying – for the presence of these hazardous elements.

Radon tests are cheap, and you can conduct them yourself.

I’m Moving Into the Basement of a Home or Residence. What Should I Know?

Basements can be a great living space, especially if you have the money and time to model the space. Yet, because they are often cold and damp, and are at the lowest point of a home they are susceptible to several pollutants.

You’ll want to test the space for the presence of radon. Because the gas often seeps into a home through cracks in the foundation, it is found in concentrated amounts in basements. If elevated radon is found, you’ll want to have a mitigation system installed to ventilate the space.

You might want to install a portable heater and/or humidifier to make the space more comfortable during certain seasons.

Finally, be sure you have a suitable exit from the house in the event of a fire or emergency. You don’t want to be trapped if something goes wrong.

Radon and Real Estate Featured

Part One: What’s the Deal with Radon and Real Estate?

What can you do about the deadly gas, radon if you are dealing with real estate? It’s a question that will plague home buyers and sellers alike. And thanks to the recent surge in the housing market, it’s even more relevant.

Many brush off the idea of a deadly, invisible and odorless gas. After all, it’s virtually undetectable so surely it doesn’t exist, right?


You see, radon is the leading cause of lung cancer in non-smokers and the second-leading cause for everyone. It is responsible for claiming the lives of more than 21,000 Americans each year. That’s just in the US, other countries such as Canada, and the United Kingdom are also affected by this natural gas.

Even scarier, it’s possible to contract radon-induced lung cancer even if you’ve never smoked a day in your life.

What is it exactly? It’s a naturally occurring radioactive gas that seeps into homes through cracks in the foundation and walls. Once inside, it collects in greater amounts effectively turning the indoor air toxic.

To combat radon, one need only install a mitigation system that ventilates the indoor space. It removes the radon gas from inside the home, and expels it into the open air outside where it can safely disperse.

A common misconception is that you won’t be able to sell a home plagued by radon, or you can’t market a home that has a radon mitigation system installed. There’s another that claims removing radon from a home is a costly fix and you should walk away – it’s really not.

We scoured the web for common real estate questions about radon. In the interest of public health and safety, we will answer some of them.

Is the Seller Responsible for Dealing with Radon, Mold or Asbestos During a Home Sale?

This question is a tough one to answer, because it depends on the terms of the sale and the selling party. For example, sale terms are going to be different when buying from a private seller versus a bank.

Modern Real Estate Property

As for who’s legally responsible, it depends on the state where you are conducting the sale.

These problems should ABSOLUTELY be solved before anyone moves into – and begins living in – the home. As for who should pay for the work, that’s something you’ll need to work out during negotiations.

If you’re the buyer you can request that the seller cover the costs out of pocket, or vice versa.

While we can’t speak on the cost of removing mold or asbestos – because it depends how much is found – we can talk about the cost of radon mitigation. The price of installing a system is not as much as you’d expect. It can range from $1000 to $5000 in rare cases, but it’s almost always on the lower side of that range.

Radon is the leading cause of lung cancer in non-smokers, so $1-5K is a small price to pay to make your new home safe.

Will Home Buyers Be Deterred By a Radon Mitigation System?

It’s possible that some uneducated buyers may be nervous about a mitigation system, but they shouldn’t be.

Turning a home down because it has a radon mitigation system is like avoiding a home that had a new roof installed. Provided the work was completed by a professional, it seems silly to walk away.

Radon levels inside a home with a mitigation system are lower than the average level of homes without. In other words, the air quality in the home is much safer.

Plus, maintenance of a mitigation system is minimal at best and they often have a warranty.

Be sure to educate potential home buyers and there should be no issues. If it helps, explain the dangers of radon and why it’s good to have a home with a mitigation system in place. If they were to find elevated levels in another home they’d have to install a system anyway.

Only Old Houses are at Risk for Radon, Right?

Older houses – especially those with a basement – are susceptible to radon, but they are not the only type of home at risk. New homes, apartments, condos, and even trailers can have high levels too.

Modern homes are built using radon-resistant materials and methods, but they can still be affected. This is why it is important that you have your home tested for radon gas, no matter where you live.

If you don’t want to hire a professional, you can always pick up a DIY test at your local hardware store or online. Just make sure you follow the directions closely so you don’t get false readings!

When Buying/Selling a Home, is Radon Testing Really Necessary?

In most states, a radon disclosure is required by law during the sale of a home.

radon gas disclosure recommends testing a homeInformation required in the disclosure varies state by state, but usually it warns homeowners about the dangers of radon. It may also include any previous testing results or info about a mitigation system where applicable.

As for radon testing, it’s not required by law in an overwhelming majority of US states.

The US Environmental Protection Agency DOES recommend everyone test their home for radon, including those being bought or sold.

Radon testing is not expensive at all, and you can do it yourself pretty easily. So it all comes down to this question: Would you rather be safe than sorry? A home with elevated radon gas levels within is a toxic and unhealthy environment.

If your answer is yes, you’d rather be safe, then have your home tested.

If you’re a seller, consider how you would feel moving into a new home that turns out to be dangerous. It’s not a positive experience at all, so you should also consider testing your home before listing it on the market.

Should I Walk Away from a Purchase if Elevated Radon Levels are Discovered?

It can be a scary prospect knowing that you’re about to buy a home that may not even be safe to live in. But there’s no reason to panic or back out of a deal, at least not immediately.

If radon is discovered while negotiations are still ongoing, you can make a request to the seller to have a mitigation system installed. If you’re negotiating with a bank – or seller who is unwilling to compromise – it will fall to you to have a mitigation system put in.

Radon in Real estateIn either case, don’t be afraid to research some local professionals and ask their opinion. Many radon contractors will provide a free on-site cost estimate after viewing the home in question.

Don’t let the discovery of elevated radon sour your deal, provided you have ample funds.

Again, you will want to fix the problem before you move into the home and begin living there. Just keep that in mind.

As a seller, this can be a frustrating experience especially when you just want to move on with your life. But consider the facts. Radon is the leading cause of lung cancer in non-smokers, and it claims the lives of more than 21,000 each year.

Even if you think it’s a bunch of nonsense, do you really want to be responsible for harming a family? Any decent human being wouldn’t. That is why you should work out some a solution with the buyer in the event that elevated radon is discovered.

National Radon Action Month Resources Guide Featured

January Is National Radon Action Month, Here’s a List of Resources to Share

January is National Radon Action month as declared by the United States Environmental Protection Agency. The idea behind it is to raise awareness about the deadly – and silent – killer radon gas. Many organizations encourage testing your home, office, or residence for the presence of radon gas and then taking action should the levels be found excessive.

While this is primary a national movement it should be noted that since Radon is a naturally occurring radioactive gas it can be a problem in any state, country, or territory. In other words, everyone – no matter where you live in the world – should take some time to test their residence. If you’ve already tested your residence then be sure to encourage friends, family, and colleagues to do so, as well.

National Radon Awareness MonthRadon IS a serious issue. It is the second leading cause of lung cancer in nonsmokers in many countries including the US, UK, Canada, and more. In the United States alone it is responsible for more than 21,000 deaths from radon-induced lung cancer. To put that into perspective, radon is deadlier than drunk driving – which is responsible for about 17,400 deaths per year – and drowning – which is responsible for about 3,900 deaths each year. If you want to see some more common accidents that radon is deadlier than take a look at our infographic on the subject.

It is odorless, colorless, and tasteless; hence why it is often called the invisible and silent killer. The only way to discover its presence in a residence or building is to conduct a test specifically for it. Luckily, testing kits are not expensive at all, and they’re not hard to acquire. You can buy them on many sites online – like Amazon – and you can often find them at a local hardware store near you.

If you’re not comfortable conducting the test yourself or would much rather have a professional opinion you can hire an experienced radon professional to conduct the exam for you.

There’s a lot more to learn about radon gas like acceptable levels, how to handle elevated levels and some other common sources for the gas. However, it’s always a good idea to have multiple sources of such information if only to check the credibility of the information you are learning.

While we do have an extensive listing of radon resources and related content here on our site, we thought it would be in everyone’s best interests if we listed several other places where you could find more information about the deadly gas. Not only will this serve as a great reference for radon-related resources, but it will also be a great guide to share with friends and family who you’d also like to educate about the problem.

Considering its National Radon Action month lets all pledge to raise awareness about the dangers of radon gas and take action wherever it may be needed!

The US Environmental Protection Agency’s Dedicated Radon Page

US Environmental Protection Agency (EPA) LogoThe United States Environmental Protection Agency is an agency or organization run by the federal government which is dedicated to protecting the health, quality of life, and environment of all within the country. They generally help enforce and create regulations – based on laws passed by congress – to help protect our health.

They have a page dedicated to educating US citizens about the dangers of Radon gas with a variety of resources. Some will explain what radon is, how it enters a home and how you can remove it. It is considered by many to be the number one source of official information on radon gas.

A lot of the statistics and facts we have collected here at Radon Resources have come from the US EPA website.

The National Radon Proficiency Program’s Database of Certified Professionals

Many states require professionals that offer radon testing and mitigation services to be nationally certified and registered. This ensures that they understand the requirements for protecting those they serve, but that they’ve also completed the necessary training to perform said work.

If you’re looking to contact a local professional that is certified to perform radon services in your area you can always pay a visit to the National Radon Proficiency Program (NRPP).

Don’t forget, we also have a National Radon Directory and our goal is to create an up-to-date, national database of radon information that is convenient to search.

The National Radon Program Services Site

If you’re looking for more basic information on radon gas and how you can protect yourself, the National Radon Program Services Site (SOS Radon) is a great place to visit. They have a ton of useful information and contact links you can use to find more about radon gas.

It’s also worth mentioning that this is the group that operates the US EPA’s 1-800-SOS-RADON hotline. When you call that number looking for more information you’ll be speaking to someone from the National Radon Program Services.

The Agency for HealthCare Research and Quality

radon gas disclosure recommends testing a homeThe Agency for Healthcare Research and Quality website is maintained by the US Department of Health and Human Services. You’ll find a host of practical information on healthcare namely as it pertains to the party you are looking up; whether that be as a consumer, healthcare provider, insurer, policy maker or researcher.

The idea is to educate the general public on common healthcare issues and topics so that everyone can make their own informed decisions. Because this site is not dedicated to providing radon resources specifically, you’ll need to conduct a search for the appropriate materials.

It’s also a great site to find common medical and healthcare information including important research data and official study findings.

Cancer Survivors Against Radon

If you’ve read about radon gas at all lately, you’ve likely heard all about the mysterious numbers – the 21,000 lives claimed every year due to radon-induced lung cancer, or one of the many others who have contracted a pulmonary illness from the gas. Rarely, have you heard from survivors directly.

This site is dedicated to sharing the stories of those who have been affected by lung cancer and have discovered elevated levels of radon gas in their homes after the fact. Many of them have never smoked a day in their life and were confused as to why they suffered from lung cancer.

It shows that radon-related deaths are not just a statistic, they really happen.

The National Cancer Institute Website

The National Cancer Institute website run by the National Institutes of Health has a variety of radon-related resources and information. Why is this so important? It’s a national institute that dedicates their resources to the research and prevention of cancer.

The Official Iowa Radon Lung Cancer Study

This recently published paper assesses and explains how radon exposure is related to the contraction of lung cancer. The lead author is R. William Field, who has a Ph.D. from the University of Iowa.

Many people ask for proof that radon exposure causes radon gas. This paper discusses the correlation between higher exposure levels and lung cancer.

The Idaho Department of Health and Welfare Radon Page

Elevated radon gas levels across the countryMany northwestern states are known for having elevated levels of radon gas, including Idaho. The Idaho Department of Health and Welfare has set up a dedicated radon page for residents where they can look up more information about the problem and how to combat it.

Most importantly, Idaho residents – and those looking for more information – can reach out to agency contacts for help in finding local testing kits and more. The Idaho Department of Health and Welfare also monitors an official hotline for Indoor Environment info which you can reach at 1-800-445-8647.

The National Radon Action Plan via the US EPA’s Website

In November 2015, the United States Environmental Protection Agency, the Department of Housing and Urban Development, the Department of Health and Human Services, and nine additional national non-governmental organizations collaborated to launch the National Radon Action Plan.

The goal is to reduce the risk of radon gas in many locations across the country including homes, schools, daycare facilities, new construction projects, and federal buildings.

National Radon Action Month Poster Contest Winners

According to the National Radon Leaders, the National Radon Action Month poster contest is:

“As part of National Radon Action Month, the American Lung Association and Conference of Radiation Control Program Directors have partnered, with support from the United States Environmental Protection Agency, to announce the winners of the 2016 National Radon Poster Contest.

The contest is held each year across the nation to raise awareness of radon gas. Radon is a naturally occurring, colorless, odorless, tasteless, radioactive gas formed by the breakdown of uranium in the soil and is found in every state. Radon can enter a home through cracks and other openings in the home and can build up to dangerous levels.

“Radon causes 21,000 lung cancer deaths each year. These deaths can be reduced, and as a nation there is an urgent need to take steps to save lives,” said Harold P. Wimmer, National President, and CEO of the American Lung Association. Radon is the leading cause of lung cancer in nonsmokers and is only detectable by performing a home test. Children ages 9-14 were eligible to participate in the contest to promote radon awareness.”

Naturally, on their site, ,they announced the poster contest winners who created the best graphics related to radon gas. The ultimate goal is to raise awareness about the deadly gas.

Updater’s Real Estate Agents and Radon Guide

One of the most common misconceptions about radon is that it’s much too expensive to deal with, especially when it comes to real estate sales or deals. For that reason, there are a lot of realtors that try to avoid discussing radon, or any radon mitigation products on a property their selling, despite the dangers. Some states require a radon disclosure message in a real estate transaction, but it doesn’t necessarily require information about the history of radon for the property being sold.

Updater’s real estate agents and radon guide is an incredibly useful resource for realtors who want to learn more.

Radon testing is cheap and can be conducted by pretty much anyone, and the testing materials are always accessible. Radon mitigation is not as costly as it may seem, especially when compared to the costs of lung cancer or getting a pulmonary illness from exposure to radon.

It’s good to get educated about the problem, even more so when you’re involved in the sale of various properties and buildings.

Carex Canada Carcinogen List

Radon isn’t the only deadly and hazardous agent you need to be wary of. Carex Canada has compiled a comprehensive list filled with over 70 carcinogenic agents. Just in case you’re not aware what a carcinogen is; they are materials or resources that can cause cancer after prolonged exposure. The risk level varies depending on the substance in question.

Be sure to take a closer look at the list to learn more.

Scientists Mapping Deadly Radon In Calgary

To see just how prevalent and deadly the silent, odorless and tasteless gas really is, scientists are studying it in the city of Calgary. More specifically, researchers are mapping homes that have shown positive for higher levels of radon gas. Interestingly enough, the concern is that Canada has a much higher action limit than the neighboring US.

Aaron Goodarzi, an assistant professor at U of C’s Arnie Charbonneau Cancer Institute who is heading up the research project, believes that Canada is at risk too.

“In Canada, we have a higher limit on what’s acceptable,” says Goodarzi. “I guess Health Canada feels Canadians have a higher tolerance for radon gas.”

Canada is no stranger to dangerous radon levels, however.

“The highest level we’ve seen was 4,300 in B.C. In Calgary, it was 4,000. They had poured concrete for the basement but not under the furnace so it was sucking air in from under the house. It was basically a radon distribution system.”

Dangerous indeed. Keep an eye on the results and data collected from this study. It will play an important role in the fight against Radon in Canada.

Radon: Eddie’s Story

Eddie is a lung cancer survivor who was exposed to radon gas. Hear his story in this informative video.

Radon Remediation (Mitigation) Tax Credit for Canadians

Several organizations are pushing for Canadian residents and businesses to receive a federal tax credit for having radon mitigation work done – which is also known as remediation. You can find out more information about the tax credit here; there’s also information on testing your home and finding a professional mitigator in Canada.

Kentucky Tobacco Policy Research Program

You’ll find a variety of materials on the Kentucky Tobacco Policy website that attests to the dangers associated with smoking and radon gas. If you didn’t already know, smokers who are exposed to radon gas are at an even higher risk of contracting lung cancer than those who don’t smoke.

Simply put, if you’re a smoker then do your best to quit, especially if you make a habit of smoking indoors. In addition, have your home tested for the presence of radon gas and take action by installing a mitigation system if the levels are high.

University of Georgia College of Family and Consumer Sciences Radon Hub

If you’re looking for more information on radon gas, mitigation, or how it affects your health this is another great place to learn. There are a variety of resources available, including info from the Georgia Radon Symposium which offers data about local radon professionals.

Utah Health Indicator Report of Radon

The information provided by the Health Indicator report is specific to Utah residents and counties in the state, but it is a great indicator of how prevalent radon is in the US. This page displays the average test results for each country in the state including a graph that goes as far back as 1990. If you live in Utah and you’re curious which areas of the state see higher levels of radon gas, this is the place to go.

Keep Checking Back for More Radon Resources!

We’ll be updating this post throughout the month of January as we discover more resources that are worth sharing with you! Please keep checking back here for an updated list of important sources!

Remember to share this guide – and your knowledge of radon gas – with as many people as possible including friends and family. Together we can save lives by preventing unnecessary exposure to radon gas!

How to Choose a Certified Radon Professional

Why would anyone need to hire a radon professional or mitigation contractor?

Radon is the second leading cause of lung cancer in the United States and many other countries including Canada and the UK. In the US alone, it is responsible for the deaths of more than 21,000 each year.

The biggest issue is that radon awareness is relatively low. Few people know it exists, and those that do often try to discredit the fact that it’s a detriment to public health.

Radon gas is odorless, colorless and tasteless which means it’s virtually undetectable. It makes sense why people would be quick to ignore it.

At low concentrations and when exposed in short bursts, there are no known side effects or symptoms. However, with a longer period of exposure those subjected to the deadly gas may develop lung cancer and any number of additional pulmonary ailments. Radon gas has been linked to chronic asthma, heart disease, cancer of the lungs and other areas of the body, respiratory infections such as pneumonia or bronchitis and more.

The saddest part about all of this is that it’s pretty easy to eliminate and remove from your home.

All you need to do is conduct annual tests for the gas, and take action if elevated levels are discovered.

Testing for Radon Gas

You can purchase a DIY radon testing kit at your local hardware store or online. If you don’t want to do it yourself, you can hire a professional radon contractor to come and take a look at your home. Most of them will offer a free consultation which includes a short-term test.

Radon Testing KitJust so you can judge the average cost, tests range from about $10 to $25 depending on where you purchase them and what kind of equipment is used. Most of them require you to place collection vials in your home for a period of time, which can be used to determine your indoor air quality.

If you conduct the test yourself, you’ll need to send the samples to a remote lab for testing via mail. The lab will perform the necessary measurements and mail the results back, or post them online if that’s an option for the particular test you purchased.

Radon Gas Mitigation

If or when elevated radon levels are discovered you’ll need to hire a licensed professional to install a mitigation system.

A mitigation system is a unique air ventilation system — usually with an electronic fan — that will remove the concentrated radon gas from your home. It does this by ventilating the gas into the open air outside, where it can disperse more evenly instead of being trapped.

The mitigation system that’s needed will depend on the layout and structure of your house. To read information about some of the more common forms of mitigation, head on over to our guide on the topic.

When hiring a professional, you’ll want to ensure they have been certified by looking for their name or business on the National Certified list (NEHA/NRSB). Don’t just take their word for it either make sure you actually see physical proof of such. Certified contractors have been to school which means they’ve passed tests on radon mitigation. In order to keep their certification, they must continue to take classes on the material. If you allow a non-certified contractor to install a system there’s a chance they could end up doing more harm than good. If a system is not up to EPA standards in some states it’s even possible that homeowners will have to pay additional costs to get it up to par.

Some additional things to look for when hiring a radon professional include:

~ Ask contractors to provide you with a copy of their Liability and Workers Compensation insurance certificate. If they do not have insurance or workers comp then you will be at a very great financial risk should any of those who are employed become injured on your property.

~ Make sure the mitigation system and included fans – where applicable – are guaranteed and covered under a warranty. If the system does not work properly after install, the contractors will return to ensure it is fixed at no cost to you. If the fans and related components malfunction, you will need to have them replaced. A guarantee will protect you in the event something isn’t working properly with the system and a warranty will protect any of the necessary components should they break or malfunction.

~ Ask for previous work references and recommendations. If the contractor cannot give them seek them out yourself. If there are no previous records of the contractor’s work then tread lightly. Another way to check on their work ethic is to ask for a couple addresses where the contractors previously did work. You can visit said addresses during an appropriate hour and speak to the residents.

~ Make sure the contractor is or is working directly with a licensed electrician. In certain states, it is actually illegal to perform electrical work without the proper credentials.

How Do You Find a Radon Professional?

Tracking down a trusted or certified radon contractor can seem daunting. The steps required are actually pretty simple once you know what to do.

Complete Construction SafetyFirst, you should visit the Department of Health website for the state you currently reside in. From there you can find information regarding indoor air quality, or more specifically radon.

The reason you should navigate to the Department of Health website is because they compile a list of every qualified radon professional that is authorized to perform mitigation and measurement work in the state. Most states require companies to register with the DOH otherwise they risk losing their certification.

You can use the DOH lists as a reference to track down a few certified radon mitigation specialists in your area. Generally, the aforementioned lists include all of the information you will need to get in touch, such as the service area, business name, address and telephone number. Such lists also include up-to-date expiration information for each contractor’s certification.

There may or may not be out of state contractors that also provide services in your particular state. If that is the case their contact information will be listed on the department of health DOH registry along with all of the other qualified contractors in your state.

Visit our National Radon Directory for more local information on radon gas and professionals in your area. You can also request a free quote from a local radon professional if you know you need one.

What to Expect from a Radon Professional You Hire

It is common practice for contractors to look at your residence and provide you with a free on-site and firm cost estimate. During that time you should also be able to view pictures of previous work the contractor has done and ask any questions you may have about the job.

The individual or company involved should offer you a definitive plan for the project up front. Before any work begins you must comb through the contract to ensure you, your home and the pending mitigation system are protected from anything shady.

At no time should the contractor become irate or give you a difficult time if you need an explanation on various portions of the contract. Pay close attention to the installation guarantee and any warranties covering hardware components or fans for your mitigation system.

Once a contract has been drawn up, the contractor should begin performing diagnostic tests in your home. This allows the specialist to detect many elements in regards to the radon levels in your home. With a diagnostic test they will be able to gauge air flow, patterns and more.

After the installation, the contractor will need to monitor the system to ensure it is working properly. If the system does not lower the radon levels in your home – and sometimes this can happen – they must take the proper measures to remedy the problem. In some cases this would mean installing a second system, or tweaking the original one. It is the contractor’s duty to choose the proper mitigation system for your home, so it should be their responsibility if the one installed does not work properly.

A contractor should never perform the final level tests on your home. They should work with you to hire or contact an outside testing professional. The extra tests will provide the necessary proof that the mitigation system is working as it should. To be quite honest, an added test should also protect the contractor should things go wrong with the system – if it was working at one point.

Will a Radon Contractor Test the Levels In Your Home?

A radon contractor can and will test radon levels in your home and this is perfectly acceptable, however there are some instances where you might want an outside source to check their accuracy. For example after a radon mitigation system has been installed in a home it’s a good idea to have a third party test the levels to cover both you and the contractor should something go wrong in the future, or should the levels change.

Before you decide to install a radon mitigation system you may also use a radon contractor to test the levels in your home. In fact, we recommend you do so that way they can offer you suggestions for potential mitigation systems. You can also perform the test yourself if you are so inclined.
