Radon is naturally in the atmosphere in trace amounts. Outdoors, radon disperses rapidly and, generally, is not a health issue. Most radon exposure occurs inside homes, schools and workplaces. Radon gas becomes trapped indoors after it enters buildings through cracks and other holes in the foundation.
When someone breathes in radon gas, it goes into their lungs, exposing them to small amounts of radiation. This may damage the cells in the lining of the lungs and increase a person's risk of lung cancer. The risk is higher in those who have lived for many years in a radon-contaminated house. Exposure to the combination of radon gas and cigarette smoke creates a greater risk for lung cancer than either factor alone.

If radon levels in your home are high, you can take steps to lower them. The most common method is to have a vent pipe system and fan installed, which pulls radon from beneath the house and vents it to the outside.
