Connecticut has a user submitted radon level of 6.94. This is based on data submitted from visitors on our site. Learn more here.
EPA Radon Levels
Connecticut has 8 counties and 4 (50%) 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. Connecticut's state radon zone average is 1.63, which is the average of all county zone ratings the EPA has assigned the state, ranking it 19 among all states.
The radon levels in the state of Connecticut are remarkably sporadic. There are quite a few areas in the state where the levels are above average and others where the levels are low or nonexistent. Regardless, there’s an increased risk for all homeowners, which is why we recommend testing exposure levels at least twice a year.

Connecticut Radon Real Estate Requirements
Does the state of Connecticut require radon testing for all real estate transactions? No
However both the state of Connecticut and the EPA recommend that a home or residence should be tested before a real estate transaction is carried out. Even though Connecticut 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. Connecticut radon mitigation is not expensive compared to the dangers and a system can be implemented in a relatively short period of time.
Connecticut 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.
