Maine Radon Levels
EPA Radon Levels
Maine has 16 counties and 12 (75%) 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. Maine's state radon zone average is 1.25, which is the average of all county zone ratings the EPA has assigned the state, ranking it 8 among all states.
The radon levels in Maine 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.

Maine Radon Contractor License Information
Does Maine require contractors to be licensed? Yes.

Maine Radon Real Estate Requirements
Does the state of Maine require radon testing for all real estate transactions? As of March 2014, rental properties must be tested for elevated radon levels by law. However, sellers are not required to test a home as part of a real estate transaction. They do have to disclose the potential of radon to the buyers.
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.
Maine 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.
Maine is the 39th most expansive in terms of size, and the 41st most populous.
Maine 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.
