Indicator Report - Radon

Why Is This Important?

The U.S. Environmental Protection Agency (EPA) estimates that about 21,000 lung cancer deaths each year in the U.S. are related to radon. Exposure to radon is the number one cause of lung cancer among non-smokers and the second leading cause of lung cancer overall. Those who smoke and are exposed to radon have an especially high risk of developing lung cancer.

Testing your home for radon levels is the only way to know if you and your family are at risk from radon, and it is inexpensive and easy. Tests can be purchased at home improvement stores, the National Safety Council, and from Utah's Division of Radiation Control. If your home radon test results measure 4.0 pCi/L or higher, the EPA recommends you take action to lower the amount of radon in your home.

A mitigation system may be installed by a certified contractor and usually costs between $800 and $2,000. For a list of qualified mitigation contractors contact the National Radon Proficiency Program, the National Radon Safety Board, or by going to the Utah Department of Environmental Quality (DEQ) and clicking on "Certified Mitigators/RRNC" (located at

Radon is a naturally occuring gas produced by the decay of uranium in soil, rock, and water. You can't see, smell, or taste radon, but it can accumulate in buildings as it seeps through cracks and holes in building foundations. The accumulation of radon in your home can pose a danger to your family's health.

Radon is the leading cause of lung cancer among non-smokers and is the second leading cause of lung cancer in America. It is responsible for about 21,000 lung cancer deaths every year. Radon is measured is picocuries per liter of air (pCi/L).

How We Calculated the Rates

Numerator: Sum of all radon level test results/number of homes tested with level over 4 pCi/L.
Denominator: Total number of homes tested/total number of homes tested.
