Radon is a radioactive gas that is naturally occurring in our area. The gas is produced from the radioactive decay of uranium that is in the soil and rock underneath us. Radon gas is colorless, odorless, and tasteless; therefore it cannot be detected in indoor air by human senses.
Behind tobacco smoke, radon gas is the second leading cause of lung cancer in the United States, accounting for an estimated 21,000 deaths per year. Studies have shown that you are more likely to develop lung cancer if you are exposed to high concentrations of radon gas over a long period of time (several years or more). The risk of developing lung cancer is greater for those who smoke, as smoking combined with radon exposure increases your risk of developing lung cancer even further.
