Radon is a naturally occurring, odorless, colorless, tasteless, radioactive gas produced from the radioactive decay of radium, found in most soils and earthen construction materials. 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. This data is collected to understand how many individuals are affected by elevated radon levels in Tennessee, and how many lives could be saved by educating the public about testing, mitigating, and building radon resistant homes.
