Radon Detectors Being Installed at Urquhart Castle, Scotland’s Most Popular Attraction

BBC News is reporting about radon detectors being installed at one of Scotland’s most popular tourist attractions, the 13th century Urquhart Castle. Essentially, the sensors will be used to test the site for high levels of radon gas. It turns out that areas nearby including the Glen Urquhart High School in Drumnadrochit were found to be plagued by a remarkably high presence of radon – seven times the recommended amount to be exact.

Why Are Radon Detectors Being Installed?

Most of the castle is actually outdoors so elevated levels aren’t expected throughout the entire property, as radon poses the biggest threat in confined spaces. Just the underground visitor centre is going to be monitored for a period of three months. Sensors, otherwise known as radon detectors, will be installed primarily as a precaution because of the test results from affected areas nearby.

Historic Scotland, who know owns the castle property, believes that the site itself is at a very low risk for radon. Since the fortress sees more than 300,000 visitors and tourists per year that’s certainly welcome news. The detectors should allow concerned parties to monitor levels on the site nonetheless.

Historic Scotland also spoke about the issue, stating that they are taking the necessary precautions to ensure the safety of guests and employees spending time at the site.

“According to the British Geological Survey radon risk map, Urquhart Castle and visitor centre are not in a high risk area for radon gas. As such, a test has not been undertaken before. However, in response to recent reported cases in the area, we have arranged for a test to be undertaken. The health and safety of our staff and visitors is of paramount importance and something we aim to preserve at all times.”

Radon is the second leading cause of lung cancer, which in itself has an exceptionally high mortality rate. That is because lung cancer symptoms don’t begin to appear until after patients have been ill for quite some time. In fact, in most cases by the time symptoms are recognized the disease has reached an incurable state.

Even worse, there are no short term symptoms of radon poisoning. Just being around high levels increases the risk of cancer – that risks increases even more so in those who have been exposed to tobacco smoke, or smoke themselves.

It’s also a common misconception that radon levels in nearby areas are an indication of what local test results may show. While there are some patterns based on geographic location, high levels of radon can pretty much be found anywhere. All residence and business owners should test their properties at least twice a year.

As for Urquhart Castle, the sensors will reveal in a few months time whether or not there are problems on the site.

Other Silent Killers Like Radon That May Be Lurking in Your Home

As this is a site dedicated to information about Radon, naturally it’s the topic we discuss most. However, radon is not the only silent killer that could be lurking in your home. There are plenty of other dangers that can cause issues with your health, including carbon monoxide, natural gas leaks, fungi, mold and bacteria.

Today, we’re going to take a quick peek at some of the other silent killers like radon.

Silent Killers Like Radon

Carbon Monoxide – This deadly gas is responsible for claiming the lives of more than 4,000 Americans every year. It is an invisible and odorless gas that is produced when appliances like your fireplace, water heater or furnace burn improperly. It can quickly fill a home, before any residents notice a problem. Symptoms associated with exposure include headaches, nausea, dizziness, fatigue, shortness of breath, unconsciousness and even death.

The only way to detect the presence of CO is to test the air inside a home for it, similar to radon. As such, several states have passed legislation that requires carbon monoxide detectors to be used in new homes.

Gas Leaks – Gas can leak into the home through one of several different appliances such as a stove or heater. As a result, this can lead to severe asphyxiation. If enough gas builds up inside a residence it can cause a dangerous explosion – most natural gas is highly flammable.

Generally, commercial gases used for fuel often give off a strong odor or smell. In the event that you do smell gas, leave the home immediately and contact the authorities. If you cannot leave for some reason, open any and all windows or doors to the outside and refrain from using anything electrical – even lights.

Fungi or Mold – Fungi and mold can build up inside a home to create what is called the Sick Building Syndrome (SBS). Mold and mildew can grow in the foundations, walls, and under carpets. All it takes is for various building materials to become wet, and stay damp for an extended period of time without being properly cleaned.

A heavily infested home can cause symptoms such as eye, nose and throat irritation as well as headaches and fatigue. The Centers for Disease Control reports that SBS can cause serious health issues for the following groups of people.

  • Infants and children
  • The elderly
  • People with asthma, allergies, or respiratory conditions
  • People with weakened immune systems

Some signs that you may have a mold or mildew problem in your home are stained ceilings, a lingering musty smell, colored spots on the wall, leaky pipes and more.

Get Help Immediately

If you suspect one of these killers may be lurking in your home seek help immediately. There are several different places you can go to find more information including the Centers for Disease Control and the Environmental Protection Agency.

Radon Guard System Receives National Building Code Certification in Canada

RADON ENVIRONMENTAL MANAGEMENT CORP. - Radon Guard™ ApprovalAs awareness about the dangers associated with radon grow so will innovation in the construction industry to protect against it – and that’s a good thing. Radon resistant construction is used when new homes and buildings are built, however it’s still possible for radon to seep into any home – even those specifically designed to keep it out.

On June 17th, 2014 at the National Research Council of Canada (NRCC) in Ottawa an event was held to celebrate the launch of Radon Guard. Radon Guard is a structural under-slab ventilation system that creates a capillary break between the ground and air barrier equipment. In layman’s terms, that means it helps ventilate gas that builds up underneath a home after seeping through the soil. In that respect, it lowers the concentration of radon in the home – helping to maintain clean air inside.

The Canadian Construction Materials Centre (CCMC) has certified Radon Guard as National Building Code 2010 compliant. Since radon resistant features are a code requirement for new construction including homes, schools and even commercial buildings, Radon Guard will certainly be useful.

Alan Whitehead, President and CEO of Radon Environmental Management believes that Radon Guard will save lives.

“Radon Guard will become the gold standard for sub-slab ventilation systems in new construction and will save thousands of lives.”

Randi Fox, the principal of Fox Architecture and founder of Radon Guard, believes much the same thing and that’s exactly why he created the system.

“Radon Guard provides many advantages over the use of the code prescriptive gravel, which can be regionally hard to find, expensive to transport and labour intensive to install. It is also a potential source of radon itself. Radon Guard will soon be readily available at most building suppliers, is competitively priced, and is fast clean and easy to install. It is a cost effective and efficient insulated under-slab ventilation system.”

Now that the technology has been certified, it would be nice to see it used elsewhere in the world such as here in the United States. Still, it’s a great leap in innovation in terms of radon resistant construction.

After all, Radon is the second leading cause of lung cancer in many countries including the US and Canada. Health Canada has estimated that more than 3,200 Canadians die each year due to radon-induced lung cancer. This is because lung cancer has a remarkably high mortality rate, as it’s often diagnosed in its later stages. Symptoms of lung cancer don’t begin to show until the late stages where patients have neared an incurable state. Worse yet, those who smoke or have been exposed to tobacco smoke have an increased risk of contracting lung cancer if they are also exposed to elevated levels of radon.

Radon resistant construction and related technology is extremely important. It’s good to see new players in the market.

Nine Counties in Florida at a High Risk for Radon

Florida is actually one of the few states in the country that requires schools and child care centers to test for radon. In addition, 24-hour care facilities such as nursing homes, prisons and even foster homes must also be tested for the deadly gas.

Building purchase contracts and rental agreements must mention that elevated radon levels have been found in the state of Florida – hopefully making more homeowners and renters aware of the problem.

Radon is a Problem in Florida

Florida Radon Levels EPA MapBelieve it or not, several counties in the state are more susceptible to radon primarily due to the abundance of rocky or clay-like soils that are rich in uranium. The element actually decays, producing a radioactive gas known as radon – which is odorless, colorless and tasteless. The gas can quietly seep into the cracks of a homes foundation, windows or walls and collect in great amounts. It can also enter a home through unfiltered well water – although in much lesser quantities usually. That being said, no matter how it enters the home, if left untreated it can build up significantly creating a toxic environment. In many cases, homeowners have no idea they are basting in a toxic home putting their entire family in danger.

Homeowner Larry Condra had a mitigation installed in his home after the levels were found to be about 7 pCi/L, well over the recommended action limit of 4.0pCi/L as set by the US EPA. After the system was installed, levels in his home reduced to 0.4 pCi/L.

“It cost me around $1,900, but it’s well worth it rather than sitting around wondering whether there’s some kind of radioactive isotope going down into my lungs that’s going to give me lung cancer somewhere down the road.”

Condra tested his home after researching about a family’s member’s thyroid cancer and finding the relation between high levels of radon and an increased risk of cancer. Although, the most common type of cancer associated with radon is lung cancer, but that’s not to say those who are exposed can’t be affected by other types.

A friend of Condra’s also had her home tested, which happened to measure in excess of 30 pCi/L.

“She said that’s really weird because you spend your whole life trying to eat right, exercise, don’t do anything unhealthy and you’re sitting in a house that’s toxic, literally.”

Florida Counties with a High Risk for Radon

According to the US Environmental Protection Agency, there are nine counties in the state of Florida that exhibit a high risk for radon, or more specifically elevated indoor levels of the deadly gas. The average screening for the areas is about 2 pCi/L to 4 pCi/L, which is relatively high and indicates a potential abundance of radon.

The affected counties include Columbia, Union, Alachua, Marion, Citrus, Leon, Hillsborough, Polk and Dade.

The problem can be made worse with modern construction methods, thanks to a shift toward more energy efficient buildings. In order to be more efficient, the affected buildings must be air-tight for several reasons, but unfortunately this can trap radon gas inside the home creating a very dangerous and toxic environment for residents.

Every one if five Florida homes has elevated radon levels, and the residents probably have no clue, as per the US EPA’s claims. More than 21,000 lung cancer related deaths can be traced back to exposure to elevated radon levels. It is the second leading cause of lung cancer, right behind smoking.

If you believe there may be a problem, the only way to find out the concentration of radon in your home is to test specifically for it. We recommend testing a home at least twice a year: once in the summer and another time in the winter. If one of those tests return elevated levels, then a long-term test is also recommended.

If levels are found to exceed 4 pCi/L then a mitigation system is necessary to continue living in the home.

The Truth About Radon and Granite Countertops

Image by Fil.Al

Image by Fil.Al

Granite countertops can actually release trace elements of the deadly and radioactive gas radon. Since radon is the second leading cause of lung cancer, which has an extremely high mortality rate, that’s more than a little disconcerting.

Of course, the United States Environmental Protection Agency has deemed most granite safe. Despite the fact that granite based countertops do release radon, it’s apparently very little – not enough to make a significant difference. That being said, how much radon is released depends on the type of rock used. The EPA does recommend that homeowners get their countertops tested if they feel there may be an issue.

With all this information out in the open, just how dangerous are granite countertops? Is there an immediate threat or not?

Radon and Granite Countertops: Dangerous or Not?

All natural materials such as stone, minerals and soil contain trace amounts of radioactive elements. These radioactive elements are called NORMs for short, or Naturally Occurring Radioactive Minerals. This means that at any given time, there are lots of things around us releasing small amounts of radioactive elements.

If we took that definition and listed every item in existence that releases radioactive material it would be seemingly endless. It includes non-plastic dishware, natural gas, phospate fertilizers and vegetables that come into contact with them, silica based glass like mirrors or windows, and even granite.

That being said, the amount of radioactive material being released is not enough to cause serious harm. It will quickly dilute in a large quantity of healthy air, even inside a residence. If you were to take a geiger counter – a device used to measure radioactive objects – it would certainly show that these materials are irradiated. However, that’s no cause for alarm.

As the US EPA states:

“In a small number of homes, the building materials (e.g., granite and certain concrete products) can give off radon, although building materials rarely cause radon problems by themselves. In the United States, radon gas in soils is the principal source of elevated radon levels in homes.”

Long story short, granite countertops are not dangerous and do not pose an immediate threat to homeowners.

Radon and Countertops: How Do You Test?

To test the concentration of radon in granite countertops – and to truly find out if yours are a threat to your health or not – you can purchase activated charcoal testing kits. Unlike testing for radon the normal way, you cannot use a standard testing kit to measure your countertops – simply placing a standard test near a granite countertop is not going to provide accurate results. You cannot use a geiger counter to properly measure the radioactive radon being released from your counter either. You absolutely must purchase a testing kit made specifically for testing radon releasing surfaces.

In addition, the kits will come with two sample containers. One must be placed on or directly near the counter while the other must be placed at least twenty feet away. The collected air samples are compared, and the results of that comparison will reveal whether or not the counters are dangerous.

The likelihood of a granite countertop contributing to a significant abundance of radon in a residence is slim. Again, in most cases there is no immediate threat and the radioactive material that is being released is not harmful.

Geographic Information Software Can Detect the Presence of Radon in the Environment

Although the risk of radon can be more prominent in certain areas of the world, its presence is not directly contingent on location. Homeowners may see elevated levels in their own residence, even if neighbors do not – and vice versa. That being said, there are places like Kentucky in the US and New Brunswick or Manitoba in Canada that see the highest instances of elevated radon.

A doctor in Halifax wants the province to purchase software that would shed some light on patient symptoms and environmental risk factors. The software is called Geomatic Information Systems, and it will essentially allow users to combine and analyze relevant data about potential risks in their area. Doctors and patients would be able to correctly identify patterns in the environment such as the presence of elevated radon in the environment.

Geographic Information Software Can Detect Common Issues Like Radon in the Environment

The software is remarkably easy to use and requires merely an area code. It will then display a web-based map with known dangers in the area. Using this information, patients and doctors can see what may or may not be the cause of health issues.

Corey Nelson, accountant manager for ESRI Canada – a company that specializes in geographic information system solutions – says that the software is extremely effective. Nelson and Dr Ajantha Jayabarathan were able to sort through 650 different patient records and identify 10 cases where the patient was experiencing respiratory problems because they were living in an area with a high radon risk. As you may already know from this site, exposure to radon significantly increases the risk of lung cancer and can cause many respiratory problems – if exposed to it for an extended period of time.

Jayabarathan further points out that the software allows her to assess more than just a patient’s symptoms. Often, health issues can be directly influenced by our environment or living conditions.

“With a tool like this I could probably also say ‘Did you know that you happen to live in a place that is high in radon? It might be to your value to have your air tested’”.

Unfortunately, Deputy Health Minister Peter Vaughan says that the software will not be made available to doctors in Nova Scotia anytime soon. It’s pretty expensive, with a price tag of about $10,000 per year, per user.

“That’s a pretty significant cost when you add up the 2,500 physicians in the province and it’s not something that we would again prioritize at this stage.”

That claim may seem a bit silly when you consider the fact that radon exposure is the second leading cause of lung cancer in many places around the world, Canada included.

The Software Could Be a Benefit Anywhere

Even though this news is coming out of Canada, the software would be beneficial anywhere. It would allow health care providers to identify common environmental problems, or more importantly an elevated presence of radon.

Perhaps we should consider using the software – expensive or not – here in the US?

Kentucky Has the Highest Rate of Lung Cancer and Related Deaths in the Country

Kentucky Mountaintop Removal Mine above town

Kentucky state residents may be surprised to know that the state has the highest rate of lung cancer and related deaths in the entire country. In fact, the death rate of lung cancer in the state is 56% higher than the national average. Some counties have death rates that are more than double the average.

Every year more than 3,500 Kentucky residents lose their lives to lung cancer.

For the most part, this can be attributed to the fact that the smoking rate of adults in the state is about 28%. When all is said and done, tobacco smoke isn’t the only cause of such frequent occurrences of lung cancer in the state. At the very least, the issue is augmented by other carcinogens.

However, lung cancer is also prominent in non-smokers because of those same carcinogens. In addition to high rates of arsenic and chromium in the air – as shown in research conducted by Tucker – central Kentucky also has the highest potential for radon gas in the entire country. This information is readily available at the US EPA website, and has been known for quite some time.

Some of the carcinogens may be from manufacturing plants and factories in the area, but radon is a naturally occurring gas that seeps up into homes, residences and businesses from the soil. Radon is odorless, colorless and tasteless. The only way to know whether or not it exists in abundance is to test specifically for it.

If radon levels in a residence exceed 4.0 pCi/L – the limit as recommended by the US EPA – then action should be taken immediately to reduce them. With the state seeing the highest rate of lung cancer in the country, action is certainly necessary.

Smoking is Not the Only Problem

Smoking is definitely a big issue, as it’s responsible for nearly eighty to ninety percent of lung cancer cases. However, many of those affected have either never smoked, or have abstained from the habit for quite some time. That is because they’re problem was likely caused by other carcinogens, like radon, asbestos and the like.

Even worse, those who have smoked – or have been exposed to secondhand smoke – are more at risk for cancer after coming into contact with radon. There’s little evidence to prove the same pattern with other carcinogens, but there may be an increase in risk if exposed to them as well.

The real issue involves time. The longer you are exposed to these carcinogens the more likely you’ll contract cancer. Time also plays a direct role in why lung cancer deaths are so high. Most lung cancer is not diagnosed until later stages of the disease, because that’s when a lot of the symptoms begin to show. Unfortunately, that also happens to be at a time when the survival rate is low.

You’re more likely to survive if the cancer is discovered early, just like you’re more likely to be healthy if you discover the existence of these carcinogens early – and then take action.

Test for the Presence of Carcinogens and Then Take Action if Necessary

It is recommended that you perform at least two air sample tests in your home every year. This is because the concentration of radon in a residence or building can fluctuate. The best times to test are during winter and summer. If one of the short term tests do indicate elevated radon levels, you might want to perform a long term test too, which involves collecting an indoor air sample for longer than 90 days. Long term tests will give a more accurate reading of the average radon levels in a residence.

If levels are found to be higher than the recommended limit, you need to take action immediately. In that case, you should schedule a consultation with a certified radon mitigation contractor. They will help you install a mitigation system that is designed to filter and clean the air in your home, or more specifically remove radon.

It should be noted however, that even after a mitigation system has been installed regular tests are still important.

It’s Time to Quit Smoking

While the aforementioned carcinogens are dangerous and require attention, the best way to reduce your risk of developing cancer is still to quit smoking. If you live in the state of Kentucky – or anywhere for that matter – and smoke regularly, then you should quit as soon as possible.

If you find it difficult to break your smoking habit, there are places where you can turn for help. You can always call the American Lung Association (ALA) Lung Help Line at (800) 586-4872 or visit the ALA website.

Great Gifts for Father’s Day: Carbon Monoxide and Radon Detectors or Radon Testing Kits

Radon Removal SystemWe’re barreling down on Father’s Day which means last minute shoppers are scrambling to find a decent gift. When we think of gifts however, most of us generally think of gift cards, tools and similar items – avoiding rather unconventional ideas. If you really want to tell Dad how much you love him and care for him, what better gift is there than one that can protect his health?

What are we talking about exactly? We’re talking about three different, but very unique gifts that would ensure Dad – and Mom – are living in a healthy environment. We’re talking about carbon monoxide detectors, radon detectors and radon testing kits.

Wait, What?

Why would anyone want to get Dad a boring gift such as carbon monoxide or radon detectors? Even worse, why would you get your Dad a radon testing kit – that will eventually require him to do a bit of work? For starters, it’s the thought that counts.

Expanding on that point, by giving Dad one of these items as a gift you’re telling him that you care about his health. You’re showing your father that you are genuinely concerned with the air quality in his home, and that you want to make sure he stays around for quite some time longer.

We don’t know about you, but we think that would mean the world to most Dads. Just knowing the fact that your children love you enough to want to ensure your safety is a gift of its own accord.

What Are They and What Do They Do?

If you frequent this site, then you already know radon exposure is the second leading cause of lung cancer in the US. According to the CDC, deaths caused by carbon monoxide poisoning aren’t far behind. From 1999-2010 there were a total of 5,149 deaths, which is an average of about 430 deaths per year. Long story short, both radon and carbon monoxide are serious health concerns.

It is recommended that all homeowners conduct a short-term radon test in their residence at least twice a year. If levels are found to exceed the recommended limit of 4.0 pCi/L then a long term test is necessary, after which the installation of a mitigation system is necessary if levels are indeed high. Before you can take action however, you need to know what the radon levels are in your home.

A radon detector conducts a series of short and long term tests to discover potential hazards. The same holds true for a carbon monoxide detector. Both types of devices will sound an alarm to alert the homeowner if dangerous levels are discovered. They are very similar to smoke detectors, except they obviously check dangerous gas levels instead.

Radon is odorless, colorless and tasteless which means it’s undetectable to humans. In fact, the only way to know you have a problem is to specifically test for one. That’s exactly why testing kits, radon detectors or carbon monoxide detectors would make great gifts.

They Make Great Gifts Period

Sure, Father’s Day will soon be over but the dangers of radon and carbon monoxide will not dissipate. If you already have a gift for Dad, or have something else in mind then consider these items as a potential gift in the future. There are many more holidays and families that could benefit from these devices.

Elevated Radon Levels are No Cause for Panic

More and more news reports are surfacing about elevated radon levels being detected in homes. Even with the news that Health Canada tests have discovered more than 1,400 homes with radon levels above the recommended action level, there’s no reason to panic, because there’s plenty of time to alleviate the problem.

In the short term, radon poisoning has no significant effects and mitigation is not as costly as you’d expect. That being said, if elevated radon levels are found in your home you should take action to reduce them as quickly as possible.

Why Not Panic, is Elevated Radon Exposure Serious or Not?

Our goal – and the goal of radon experts – is not to scare the general public, but instead to make them more aware about the dangers of the odorless, tasteless and colorless gas. It isn’t much of a problem outdoors, out in the open, but when it’s confined and collects inside a building it can cause some pretty serious health issues over an extended period of time. Furthermore, when combined with exposure to tobacco smoke, it increases the risk of lung cancer exponentially.

Dr. Daniel Cluff, from the University of Exeter says that there’s no reason to be alarmed by the influx of recent reports.

Radon exposure is the second leading cause of lung cancer behind smoking and before second-hand smoke. That should provide a little perspective to some, especially when you consider how serious second-hand tobacco smoke exposure can be. Just think radon exposure is much more prominent than that.

The real dangers come from years and years of prolonged exposure. That’s not to say there’s no short term harm, but at the very least there are no visible symptoms of it. That is exactly why there’s no reason to panic about high radon levels in your area, or if they are discovered in your home.

Test Before You Worry

It is recommended that you test your home for radon at least twice a year, once in the summer and a second time in the winter. This is because the levels can fluctuate greatly, thanks to a lot of different factors like the current season, amount of air flow in the home, and even soil makeup beneath your foundation. Some areas are more susceptible to radon however it can be found anywhere. Long story short, every homeowner should have their home tested regardless of location.

What if Radon is Found?

There will always be a small amount of radon in a home, but if levels are detected above the recommended action limit you’ll need to do something about it. What steps you will need to take will largely depend on the concentration of radon in the home.

In simple cases, homeowners can install a high-efficiency HEPA filter which screens and filters out dangerous particles in the air, like radon. In more extreme cases, homeowners may have to hire a contractor to install an advanced mitigation system which lowers the concentration of radon by removing it from affected areas of a home.

Be sure to read further about elevated radon levels, general dangers and how to mitigate a problem if one is discovered.

Digital Radon Detector or Standard Testing Kit?

It is highly recommended that all homeowners test their residence for radon at least twice a year. In regards to that, we are talking about short term tests that are conducted over a series of two to seven days. Long term tests – which are much more accurate – are generally taken over an excess of ninety days. While long term tests do provide a more accurate rating of radon levels in a home throughout the year, short term tests provide results much faster. If you’re moving into a new home, or if you believe there is an exposure problem it’s likely the best option.

What About a Radon Detector?

All that aside if you already live in the home you might be better off picking up a radon detector. There are several different kinds of course, but for the most part they all collect long term readings over an extended period of time. They work exactly like a smoke detector, sending out audio alerts if elevated levels have been found.

Unfortunately, most radon detectors have been designed with professionals in mind – or more specifically contractors and radon mitigators. This can create a difficult installation process for a few different reasons.

First, professional radon detectors must be calibrated before they can provide accurate readings. This usually cannot be done in the home by inexperienced users, so they must be sent out to calibration specialists. This takes time and can cost between $100 to $150 plus shipping for the calibration procedure.

This is why radon testing kits are recommended more often.

One of the best options for consumers and homeowners is the Safety Siren Pro Series brand. It was designed for the average consumer in mind and it has also been evaluated by the US Environmental Protection Agency.

How Do They Work?

Safety Siren Pro Series 3 radon detectorWe’re going to talk about the Safety Siren Pro Series 3 radon gas detector, but there are other models available on the market – most of which work in the same fashion.

The detector can be quickly and easily installed, as it plugs directly into a standard electrical outlet. The integrated LED display can output both the short and long term readings of radon gas levels. If the radon levels exceed the recommended limit – 4.0 pCi/L – at any given time then an alarm will sound. You can program the detector to monitor short term, over 48 hours or long term, over a year or more.

One of the best uses for a radon detector is to monitor levels after a radon mitigation system has been installed in a home. Just because a mitigation system has been installed doesn’t mean you should stop testing radon levels. They can still grow to be over the recommended limit, especially if the mitigation system was setup improperly.

Thanks to the easy install feature, you can move the radon detector around your home freely. However, it is essential that you measure the lowest living area where you spend most of your time at least once.

The radon detector should be placed at least 3 feet away from openings in the exterior of the home such as windows, doors or even ventilation exits. It must also be at least one foot from an exterior wall, and at least 20 inches from the floor.

When conducting a short term test, you should keep all windows closed, as well as the doors – whenever possible. You should also turn off all window-based fans. Central air-conditioning units or window air conditioners are surprisingly okay to leave on, however.

After 48 hours or so, the detector will display the initial readings. Over time the reading will be adjusted as the detector continues to monitor levels.

Should I Get a Test Kit or Radon Detector?

The real answer here is that you should probably get both. The testing kit should be used first to find an initial reading then the detector should be installed. It is extremely important that you use a detector or test regularly after a mitigation system has been installed in your home. You want to make sure the system is working properly, and that it continues to do so over time.

As for whether you rely on a standard testing kit or detector – that’s up to you in the end.
