Radon Occurs Naturally

Radon is a naturally occurring radioactive gas that comes from the breakdown of uranium in the soil.

• It's a gas that moves up through the soil to the atmosphere.

• ​High radon levels have been found in all 50 states and in all parts of Colorado.
• In Colorado, about half the homes have radon levels higher than the U.S. Environmental Protection Agency recommended action level of 4 picoCuries per liter (pCi/L).
• Radon has no color, odor or taste and doesn't cause short-term symptoms of illness.
• Radon causes cancer.
  • It's estimated to cause about 21,000 lung cancer deaths per year in the United States.
  • It's the second leading cause of lung cancer in the U. S, according to the surgeon general.
  • Only smoking causes more lung cancer deaths.

​Radon moves from uranium-bearing granite deposits in the soil to the atmosphere.

• Your home sits on radon's pathway from the soil to the atmosphere.
• Your home is usually warmer and has lower air pressure than the surrounding soil, so gases in the soil, including radon, move into your home.
• The most common routes are:
  • Spaces between basement walls and the slab.
  • Cracks in foundations and/or walls.
  • Openings around sump pumps and drains.
  • Construction joints and plumbing penetrations.
  • Crawl spaces.
  • Well water with high radon concentrations.

• ​​The age and/or type of home doesn't matter when it comes to whether high levels of radon are present.
