Radon is a colorless, odorless gas that occurs naturally in soil, rock, groundwater and outdoor air. Radon gas is given off by radioactive elements such as uranium and radium. Radon becomes hazardous to human health when it accumulates inside buildings. The Environmental Protection Agency (EPA) considers radon to be a leading cause of lung cancer in the U.S., second only to smoking. The EPA, National Radon Proficiency Program (NRPP) and the American Association of Radon Scientists and Technologists (AARST) have issued guidelines for safe levels of radon and recommendations for remediation when radon levels exceed the “action level” of 4.0 picoliters (pCi/L). Minnesota Department of Health (MDH) requires radon measurement professionals to be licensed by the State of Minnesota as of January 1, 2019.
