Minnesota health officials urge residents to test their homes for radon this winter to prevent health risks.
Radon, a colorless and odorless gas found naturally in Minnesota soil, can enter homes through cracks and openings in walls or foundations. Prolonged radon exposure is the leading cause of lung cancer among non-smokers, contributing to about 21,000 lung cancer deaths annually in the U.S. Health officials emphasize the importance of testing homes, especially during the winter months when radon levels can accumulate with windows and doors sealed.
Residents are encouraged to test every five years or sooner if significant renovations or HVAC changes have occurred. Free or low-cost test kits are available through local public health offices, and kits can also be purchased at hardware stores or online for $12.95 at mn.radon.com.
MDH reports that Minnesota’s average home radon level is three times the national average, with Southwest Minnesota showing some of the highest levels. Testing rates are lowest in areas with higher poverty, such as Minneapolis and St. Paul urban centers.
Mitigation systems using venting pipes and fans are recommended for homes with high radon levels. The MDH website provides a list of licensed radon professionals and additional resources.
