Radon is a colorless, odorless gas that occurs naturally when uranium in the soil breaks down. If inhaled, radon can cause damage to your lung tissues and can lead to lung cancer.
Radio gas typically moves up through the ground to the air above and into your home through cracks and other holes in the foundation. The radon then becomes trapped inside your home, where it could build up to dangerous levels.
Radon has been found in every state, in brand new homes and old homes, as well as homes with and without a basement. There are ways to test for radon in your home and, if necessary, reduce radon levels. The best source for radon gas information and remediation is www.epa.gov/radon.
