Minnesota Radon Information

Minnesota Radon Levels

Minnesota has a user submitted radon level of 6.93. This is based on data submitted from visitors on our site. Learn more here.

EPA Radon Levels

Minnesota has 87 counties and 68 (78%) have been assigned Zone 1 counties by the EPA. Zone 1 counties have the highest potential to have homes test higher than 4 pCi/L. Minnesota's state radon zone average is 1.22, which is the average of all county zone ratings the EPA has assigned the state, ranking it 7 among all states.

The radon levels in Minnesota are above average in many areas of the state. According to the Minnesota Department of Health two out of every five homes in the state have elevated radon levels. Nearly 80% of the counties have been rated as high radon zones. In addition, the state’s geology and climate are known for producing high amounts of radon. As such, there’s an increased risk for all homeowners, which is why we recommend testing exposure levels at least twice a year.

Minnesota Radon Contractor License Information

What are the licensing requirements? There are no state mandated requirements to become a licensed radon contractor in Minnesota. Those looking for a radon certification can take qualified third party courses that are offered through the NRPP or AARST.

Minnesota Radon Real Estate Requirements

Does the state of Minnesota require radon testing for all real estate transactions? No, however as of January, 2014 the Minnesota Radon Awareness Act requires home sellers to educate the buyer on the hazards of radon. Buyers must disclose the following information where applicable:

1. Whether or not a radon test - or tests - have occurred on the property
2. The most current records and reports pertaining to radon concentrations within the residence
3. A description of any and all radon concentrations, mitigation, or remediation information
4. Information regarding the radon mitigation system, including system description and documentation, if such system has been installed in the dwelling
5. A radon warning statement or statement that brings the buyers attention to the potential existence of radon
6. A copy of the Minnesota Department of Health publication entitled "Radon in Real Estate Transactions."

Even though the state does not require testing, we certainly recommend you have one done before you purchase a home. If you decide to perform a test after and find elevated levels, there is no reason to panic. Radon mitigation is not expensive compared to the dangers, and a system can be implemented in a relatively short period of time.

Minnesota Radon Map

Zone 1 (1): Potential for radon levels above 4 pCi/L according to EPA
Zone 2 (2): Potential for radon levels between 2 pCi/L and 4 pCi/L according to the EPA
Zone 3 (3): Lowest EPA level with expected radon levels at or below 2 pCi/L
Disclaimer: It is strongly recommended that all households, schools and office spaces test radon levels individually. The EPA Radon Zone data is not an indicator of individual test results, but a guideline for strategic planning. Toxic radon levels can be found in all counties, regardless of their zone rating. While we make efforts to keep this information up to date, it is derived from third­party sources which may not be accurate or reflect the most current statistics.

About Minnesota
