January is Radon Action Month in Michigan
Governor Gretchen Whitmer has declared January 2026 as Radon Action Month in Michigan, and she encourages all Michigan residents to learn more about this environmental hazard and test their homes during this winter’s heating season.
Radon is a naturally occurring radioactive gas produced by the natural decay of uranium found in all soil types. Radon gas enters buildings from the soil and can accumulate to high concentrations indoors. You cannot see, smell, or taste radon, and there are no short-term side effects that could cause alarm or warn of its presence.
However, long-term exposure to radon increases the risk of developing lung cancer, which accounts for more deaths in both men and women than any other form of cancer in the United States, according to the Michigan Department of Environment, Great Lakes, and Energy (EGLE). The department aims to increase awareness of health risks associated with elevated indoor radon levels, promote home testing, and encourage citizens to take action to reduce exposure if elevated radon levels are found.
Behind smoking, radon is the leading cause of lung cancer for nonsmokers and is considered a leading environmental cause of cancer deaths in the United States. Current and former smokers have significantly higher radon induced lung cancer risks.
The U.S. Environmental Protection Agency (USEPA) estimates that radon is responsible for about 20,000 lung cancer deaths in the United States each year.
Radon testing continues to be important as many Michiganders statewide remain unaware of the hidden dangers of exposure to radioactive radon gas. Testing is easy, inexpensive, and is the only way to determine if a radon problem exists.
Residents are encouraged to test for radon every two to five years. If a radon mitigation system is currently installed in the home, residents are encouraged to re-test every two years to make sure that radon levels remain below the federal action level of 4 picocuries per liter of air (4 pCi/L). In Michigan, approximately one in every four Michigan homes are projected to have radon levels exceeding 4 pCi/L. Elevated radon levels have been found in all 83 Michigan Counties.
Radon poses a serious public health threat in our communities statewide, but high radon concentrations are also easily fixed. This year, residents have several ways to learn more about radon in Michigan:
- EGLE has produced a four-part podcast series moderated by Jerry Hodak. This series covers many common interest topics such as radon origins and health effects; radon testing best practices; test results and radon reduction methods; and retesting frequency and mitigation system maintenance. Check out the podcast series.
- EGLE also has an interactive map of Michigan Indoor Radon Test Results. Learn about radon testing in your neighborhood.
- Radon test kits may be obtained from many of Michigan’s Local Health Departments. This January take action and contact your local health department for a radon test kit.
