Missouri Radon Levels

Missouri has a user submitted radon level of 6.83. This is based on data submitted from visitors on our site. Learn more here.

EPA Radon Levels

Missouri has 108 counties and 11 (10%) 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. Missouri's state radon zone average is 1.96, which is the average of all county zone ratings the EPA has assigned the state, ranking it 31 among all states.

The radon levels in Missouri are above average in many areas of the state. As such, there’s an increased risk for all homeowners, which is why we recommend testing exposure levels at least twice a year.

Missouri Radon Contractor License Information

Does Missouri require contractors to be licensed? No.

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


Missouri Radon Real Estate Requirements

Does the state of Missouri require radon testing for all real estate transactions? No

However both the state of Missouri and the EPA recommend that a home or residence should be tested before a real estate transaction is carried out. Even though Missouri does not require radon testing, we certainly recommend you have a test performed before you purchase a home. If you decide to perform a test after and find elevated levels, there is no reason to panic. Missouri radon mitigation is not expensive compared to the dangers and a system can be implemented in a relatively short period of time.


Missouri Radon Map

Map of Missouri Radon Levels

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.
