- Radon is a cancer-causing, radioactive gas that comes from the natural breakdown of uranium in soil, rock and water and gets into the air you breathe.
- You can’t see, smell or taste radon, but it may be a problem in your home or business.
- Radon is estimated to cause many thousands of deaths each year. That’s because when you breathe air containing radon, you can get lung cancer.
- The Surgeon General has warned that radon is the second leading cause of lung cancer in the United States today. Only smoking causes more lung cancer deaths. If you smoke and your home has high radon levels, your risk of lung cancer is especially high.
- Radon can be found all over the U.S.
- Radon can get into any type of building — homes, offices, and schools — and result in a high indoor radon level. But you and your family are most likely to get your greatest exposure at home, where you spend most of your time.
Deaths per year
*Radon is estimated to cause about 21,000 lung cancer deaths per year, according to EPA’s 2003 Assessment of Risks from Radon in Homes (EPA402-R-03-003). The numbers of deaths from other causes are taken from the Centers for Disease Con- trol and Prevention’s 1999-2001 National Center for Injury Prevention and Control Report and 2002 National Safety Council Reports.

- 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 (EPA) recommended action level of 4 picoCuries per liter (pCi/L).
