Massachusetts Radon Levels

The Environmental Protection Agency (EPA) has identified 4 pCi/L is the threshold at which a home should take action to mitigate radon. In Massachusetts, three counties – Essex, Middlesex, and Worcester – have been designated high-risk, indicating that they have a greater potential for indoor concentrations of radon to exceed 4 pCi/L. With the exception of Suffolk County, the remaining counties in the state are designated moderate risk, with indoor radon levels expected to fall between 2 pCi/L and 4 pCi/L. Suffolk is the lone county in Massachusetts that carries a low risk designation. Despite these labels, no home is ever known to be 100% safe until tested. You can pick up a test kit at a local hardware or home improvement store, or follow the link below and we're happy to send one to you.

*the map above is not 100% accurate as there are many factors for what radon levels actually are in every area, This map should only be used as a reference to the areas and what the areas average indoor radon levels may be. No matter what your radon level can only be determined by an actual radon test administered by or ordered from a professional radon testing facility.
