Why is radon dangerous?
You can’t see or smell radon because it is a colorless, odorless gas. Radon is a decay product of uranium and occurs naturally in soil and rock, and therefore radon levels can vary home to home. Other sources of radon include well water and building materials. Radon is a radioactive gas and has been identified as a leading cause of lung cancer, second only to cigarette smoking in the United States. EPA’s most recent health risk assessment estimates that 21,000 lung cancer deaths each year are due to radon.
