On this page: EPA RECOMMENDS If you are buying or selling a home, have it tested for radon. For a new home, ask if radon-resistant construction features were used and if the home has been tested. Fix the home if the radon level is 4 picocuries per liter (pCi/L) or higher. Radon levels less than 4 pCi/L still pose a risk and, in many cases, may be reduced. Take steps to prevent device interference when conducting a radon test. EPA estimates that radon causes thousands of cancer deaths in the U.S. each year. *Radon is estimated to cause about 21,000 lung cancer deaths per year, according to EPA's 2003 Assessment of Risks from Radon in Homes (EPA 402-R-03-003). The numbers of deaths from other causes are taken from the Centers for Disease Control and Prevention's 2005-2006 National Center for Injury Prevention and Control Report and 2006 National Safety Council Reports.
