What is Radon?

Radon is a colorless, odorless, radioactive gas that occurs naturally when uranium in soil and rock breaks down. It can seep into buildings through cracks in foundations, floors, and walls. Radon is the second leading cause of lung cancer in the United States after smoking.

EPA Action Level: The EPA recommends taking action to reduce radon levels when they exceed 4 pCi/L (picocuries per liter). Many health experts recommend mitigation at levels above 2 pCi/L.
