Michigan

Radon gas can be a prevalent problem in Michigan, with an estimated 1 in 8 homes having elevated levels of radon. The Michigan Department of Environment, Great Lakes, and Energy (EGLE) recommends that all homeowners in Michigan test their homes for radon gas, especially if they are buying or selling a home. The EGLE provides resources and information on radon testing and mitigation on its website. It also maintains a list of licensed radon testing and mitigation professionals in Michigan. Michigan law requires that radon testing be conducted in schools and daycare centers. The EGLE provides information on its website about radon testing in schools and offers a radon testing kit loan program to schools. Overall, the radon gas situation in Michigan is a serious concern, and homeowners and residents are encouraged to take steps to protect themselves and their families. Testing for radon and mitigating elevated levels can help prevent lung cancer and other health problems associated with radon gas. 

United States EPA State Map of Radon Gas Concentration

The U.S. EPA and the U.S. Geological Survey have evaluated the radon potential in the U.S. and have developed this map is to assist National, State, and local organizations to target their resources and to assist building code officials in deciding whether radon-resistant features are applicable in new construction. This map is not intended to be used to determine if a home in a given zone should be tested for radon. Homes with elevated levels of radon have been found in all three zones. All homes should be tested regardless of geographic location. The map assigns each of the 3,141 counties in the U.S. to one of three zones based on radon potential. Each zone designation reflects the average short-term radon measurement that can be expected to be measured in a building without the implementation of radon control methods. The radon zone designation of the highest priority is Zone 1.

	Zone 1	Highest Potential (greater than 4 pCi/L)
	Zone 2	Moderate Potential (from 2 to 4 pCi/L)
	Zone 3	Low Potential (less than 2 pCi/L)
