Radon is an odorless, colorless, naturally-occurring gas formed by the decay of radioactive materials. Radon itself is radioactive and poses a health threat when sufficient concentrations collect in enclosed areas such as basements and crawl spaces. Radon is the second leading cause of lung cancer overall and the leading cause among nonsmokers. Iowa has the largest percentage (71.6%) of homes above the US Environmental Protection Agency action level of 4pCi/L, in the US.
