EGLE seeking homeowners with radon mitigation systems for participation in a new study

The Indoor Radon Program at the Michigan Department of Environment, Great Lakes, and Energy (EGLE), in partnership with the American Association of Radon Scientists and Technologists (AARST), has kicked off a study of radon mitigation systems installed in Michigan.

The program is seeking homeowners with a radon mitigation system for voluntary participation in the radon mitigation system study.

Radon is a serious health hazard known to be the leading cause of lung cancer for never smokers. When installed properly, radon mitigation systems are effective at reducing indoor radon concentrations below the USEPA Action level of 4 picocuries per liter of air (pCi/L). The goal of this study is to survey existing mitigation systems installed in the state for radon mitigation system build quality, as compared to the current AARST radon mitigation standards.

The Indoor Radon Program is a non-regulatory program whose purpose is to increase awareness of the health risks associated with exposure to elevated indoor radon levels, encourage testing for radon, and encourage citizens to take action to reduce their exposure once elevated radon levels are found.

EGLE does not currently license or otherwise regulate the installation of radon mitigation systems or the radon professionals who install them. However, the department would like to inspect radon mitigation systems to determine if it was installed properly following nationally recognized radon mitigation standards.

There is no charge for the inspection, which will be performed by a representative under contract with AARST. The inspection should take approximately 30 to 45 minutes. If you have a radon mitigation system in your home and would like to have your system inspected as a part of this study, please complete the registration form.

To learn more, please see the Radon Mitigation Study Web page and Frequently Asked Questions.

The selection process will prioritize homes with radon mitigation systems installed within the last five years. Efforts will be made to have a representative sample size across the state and include as many mitigators as possible.

Participation in the study will help ensure radon mitigation systems are installed properly in Michigan, which will help protect, maintain, and improve the health of Michiganders.

Submission of an application to participate in this study does not guarantee selection.

Questions about participation in this voluntary radon mitigation system study can be directed to Les Smith, III, indoor radon specialist, in the Radiological Protection Section of the Materials Management Division within EGLE; by phone at 800-723-6642; or by e-mail at
