Radon is a radioactive gas that is colorless, tasteless, and odorless. Radon comes from the breakdown of uranium in soil, rock and water and can enter your home and any type of building through cracks and openings. Your home may trap radon inside, where it can build up to levels that may impact your health as you breath in air containing radon.

Why Exposure is a Concern

Radon is the second leading cause of lung cancer. Lung cancer deaths caused by radon gas are estimated between 15,000 to 22,000 per year. 

Madison County is a high radon risk county. 

Not everyone exposed to radon will get lung cancer, but the greater the radon level and the longer the exposure, the greater the risk of developing lung cancer.
