Radon is a naturally occurring radioactive gas that is released during the decay of uranium, which is found in most rock and soil. Radon is odorless, invisible and without taste. It is the second leading cause of lung cancer in the United States, and it is the No. 1 cause of lung cancer among non-smokers.
Radon does not generally present a health risk outdoors but It can build up to dangerous levels inside a house.
Citizens can receive FREE radon test kits by filling out a request form on the TDEC website, or by calling the Tennessee Radon Program hotline at 1-800-232-1139. High radon levels in a home can be mitigated – often through measures such as ventilation. TDEC officials highly recommend using a certified professional for mitigation.
