Indoor Radon

Radon is a naturally occurring, radioactive gas that you can’t see, taste or smell. It is produced by the breakdown of uranium in soil, rock and water. High levels of radon have been found in all 50 states. Indoor radon is the second leading cause of lung cancer after smoking. Radon contributes to an estimated 7,000 to 30,000 lung cancer deaths each year. A combination of smoking and high levels of radon in your house increases your risk.

Radon enters homes most commonly through:

  • cracks in foundations;
  • openings around sump pumps and drains;
  • construction joints;
  • cracks in walls;
  • crawl spaces; and
  • in some cases from well water.
