January is National Radon Month and the EPA is encouraging everyone to test and take preventive measures to reduce the radon threat.
EPA estimates that one in 15 homes will have a radon level of four PicoCuries per liter (pCi/L) of air or more, a level the agency considers high. Radon is the second leading cause of lung cancer behind smoking.
