What is Radon?
Radon is a colorless, odorless, natural occurring gas that is found in soil and released into the air as uranium is broken down. Radon released into the air can build up, causing critical long-term health effects. 1 in 15 homes in the U.S. is estimated to contain elevated levels of radon. The radon risk in New England, along with much of the northeast and some parts of the midwest is generally higher than other parts of the country with predicted average indoor radon screening levels greater than 4 pCi/L.
Radon is the second leading cause of lung cancer in the U.S. after smoking. The only way to discover if you have a radon problem is to test the air or water in your home for elevated levels of radon.
Regular radon testing and mitigation can help you have a healthier, safer home for you and your family.

New England is an EPA Radon Hot Zone!
- Zone 1: Counties with predicted average indoor radon screening levels greater than 4 pCi/L
- Zone 2: Counties with predicted average indoor radon screening levels from 2 to 4 pCi/L
- Zone 3: Counties with predicted average indoor radon screening levels less than 2 pCi/L
