Radon is a colorless, odorless and tasteless radioactive gas that occurs naturally in most rocks and soil. It is produced by the breakdown of uranium in soil, rock and water. Radon is harmlessly dispersed in outdoor air, but when trapped in buildings can increase the risk of lung cancer, especially at elevated levels. In a National Health Advisory issued on January 13, 2005, U.S. Surgeon General Richard H. Carmona warned the American public about the risks of breathing indoor radon. Radon is not known to cause other illnesses or problems, such as upper respiratory infections, colds or allergic reactions. Its only known health effect is an increased risk of developing lung cancer. However, as with those who smoke, not everyone exposed to high levels of radon will develop lung cancer, and the time between exposure and the onset of cancer may be many years.
