The U.S. Environmental Protection Agency (EPA) estimates that about 20,000 lung cancer deaths each year in the U.S. are related to indoor exposure to radon. The only way to know whether indoor radon levels are elevated is to test the indoor air. This report contains findings that describe the problems that have been identified and correctives that are recommended. The purpose of this evaluation was to determine how EPA ensures that: radon testing devices provide accurate data on indoor radon risks; and radon testing laboratories accurately analyze and report indoor radon results.
