Massachusetts Radon Information

Massachusetts Radon Program:

Radon Website: Website
Radon Contact: William Bell
Active Radon Program: Yes
Require License for Radon Professionals: No

Massachusetts is the 7th smallest state and the 14th most populous. It also happens to be the third most densely populated state in the entire US. Massachusetts does have an active radon program, dedicated to educating citizens about the risks associated with the deadly gas. You can find more information on Radon, testing and mitigation at the official page.

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

Massachusetts Radon Levels

Map of Massachusetts 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.

Massachusetts Radon Statistics

Massachusetts has 14 counties and 3 (21%) 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. Massachusetts's state radon zone average is 1.86, which is the average of all county zone ratings the EPA has assigned the state, ranking it 28 among all states.

Massachusetts Radon Contractor License Information

Does Massachusetts require contractors to be licensed? No.

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

Massachusetts Radon Real Estate Requirements

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

However both the state of Massachusetts and the EPA recommend that a home or residence should be tested before a real estate transaction is carried out. Even though Massachusetts 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. Massachusetts radon mitigation is not expensive compared to the dangers and a system can be implemented in a relatively short period of time.
