Radon is a naturally occurring, invisible, odorless, tasteless gas that is dispersed in outdoor air. However, radon can reach harmful levels when trapped in a home. Scientists are concerned about the health risk of radon. There is overwhelming proof that exposure to elevated levels of radon causes lung cancer in humans.
Radon is the second leading cause of lung cancer in the U.S. after smoking and the leading cause of lung cancer among non-smokers.
