The National Safety Council's Radon Poster Contest, conducted in partnership with EPA and U.S. Department of Agriculture, is intended to raise awareness of radon and the importance of testing homes and fixing elevated levels. Radon is a naturally occurring, invisible, odorless, tasteless, radioactive gas that is harmlessly dispersed in outdoor air, but which can reach harmful levels when trapped in buildings. It originates from deposits of uranium in soil, rock and water.
