Radon is an invisible and odorless gas. It comes from the soil, rock and water under homes and other buildings. It moves up through the ground to the air above and into a home through cracks and other holes in buildings. Radon can be found all over the U.S.

Radon gas decays into radioactive particles that can get trapped in the lungs. This can damage the lungs. Breathing radon gas for a long time can cause lung cancer.

Most homes don't have a radon problem, but there is a simple test to find out if there is a high radon levels in a home. The good thing is that homes with high levels of radon can easily be fixed.

All homes with basements should be tested for radon.
