  Radon is a colorless, odorless gas that arises naturally within the ground from the decay of radioactive elements. It is the leading cause of lung cancer among non-smokers. The action level for home exposure is 4 picocuries of radion per liter of air (4 pCi/L).According to the US EPA, the average radon level in American homes is 1.25 pCi/L, and 6 million homes have levels of 4 pCi/L and above.
