Questions about radon in Bangor

What radon zone is Bangor in?

EPA's Map of Radon Zones classifies counties, not cities. Penobscot County is in Zone 1 (highest predicted potential). A zone is a prediction for a whole county and never tells you the level in one home.

Should I test my home in Bangor?

Yes. Testing is the only way to know the radon level in a specific building. EPA recommends fixing a home when the radon level is 4 pCi/L or higher. EPA recommends considering a fix when the level is between 2 and 4 pCi/L. How to test a home.
