Radon gas is a leading environmental cause of cancer in the U.S. Test your home today

"Protect your family from radon. Test your home." graphicGov. Gretchen Whitmer has declared January 2022 as Radon Action Month in Michigan, and she encourages all Michigan residents to learn more about this environmental hazard and test their homes during the heating season.

Radon is a naturally occurring radioactive gas. 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), which 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 once elevated radon levels are found.

Behind smoking, radon is the second leading cause of lung cancer and considered a leading environmental cause of cancer deaths in the United States.

The U.S. Environmental Protection Agency estimates that radon is responsible for about 20,000 lung cancer deaths in the United States each year.

Radon testing takes on increased importance due to many Michiganders now working from home. Testing is easy, inexpensive and 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 was previously installed in the home, residents are encouraged to test every two years to make sure that radon levels remain in the acceptable range.

One in every four Michigan homes is expected to have radon levels exceeding the federal action level of 4.0 picocuries per liter. Elevated radon levels have been found in all 83 Michigan counties. Radon poses a serious threat to our community's health, but high radon concentrations also are easily fixed.

For more information about radon testing and mitigation, including resources for homeowners, builders, realtors, teachers and healthcare providers, go to, or call EGLE's Indoor Radon hotline at 800-RADONGAS or 800-723-6642.  Residents may pick up radon test kits from their local health departments for a small fee or in some case free during Radon Action Month. A national radon laboratory also offers Michigan residents radon test kits at a discounted rate. Both short- and long-term test kits can be purchased online and shipped right to your doorstep.
