Minnesotans Urged to Test Homes for Dangerous Radon Levels

Residents of Minnesota are being urged to test their homes for radon, a colorless and odorless radioactive gas that poses significant health risks. According to the Minnesota Department of Health (MDH), approximately 40% of homes in the state may have dangerous levels of radon, particularly in south and southwestern counties.

Radon is the leading cause of lung cancer among non-smokers and typically enters homes through cracks or openings in walls or foundations. Dan Tranter, supervisor of the MDH Indoor Air Unit, emphasized the importance of testing for this gas, stating, “You can’t see or smell radon, so the only way to know how much is in the air is to test for it.”

Understanding Radon and Its Health Risks

Radon releases radioactive particles that can damage lung tissue when inhaled. The geological and climatic conditions in Minnesota contribute to elevated radon levels, especially during winter months when home heating systems can draw radon gas from the soil into indoor spaces. MDH warns that there is no safe level of radon exposure, making regular testing essential.

Tranter advises homeowners to test for radon every two to five years. If a test reveals radon levels at or above 4.0 picocuries per liter, the installation of a radon mitigation system is strongly recommended to lower those levels.

Free Testing Kits Available Across Minnesota

Minnesota residents can access free or low-cost radon test kits through various public health departments. Dakota County offers free test kits at the Northern Service Center in West St. Paul and the Western Service Center in Apple Valley. Residents can also receive guidance through phone consultations with Dakota County Public Health staff.

In Washington County, free test kits are available during operating hours at multiple locations, including the Cottage Grove Service Center and the Stillwater Government Center. Ramsey County residents can order a radon test kit for just $2 online. Additionally, homeowners in other Minnesota counties can obtain kits from Air Chek for $12.95 at mn.radon.com.

The push for testing reflects a broader commitment to public health and safety in Minnesota. As the state grapples with the challenges posed by radon, officials continue to stress the importance of awareness and proactive measures to mitigate this invisible threat.
