Radon Risk in St. Cloud & Stearns County
Minnesota consistently ranks among the highest-radon states in the country. The Minnesota Department of Health estimates that approximately 2 in 5 Minnesota homes have radon levels above the EPA action level of 4 pCi/L — and Stearns County is no exception.
Radon is a naturally occurring radioactive gas that seeps into homes from the soil and bedrock beneath your foundation. It's colorless, odorless, and tasteless — impossible to detect without testing. Long-term exposure is the second leading cause of lung cancer in the United States, responsible for about 21,000 deaths per year.
If you haven't tested your St. Cloud home, or if results came back above 4 pCi/L, the EPA recommends mitigation. Radon Stoppers can typically reduce levels below 2 pCi/L — often down to 1 pCi/L or less.

St. Cloud and Stearns County: Central Minnesota's Radon Risk Extends Far Beyond the Cities
St. Cloud is the largest city in central Minnesota and the hub of Stearns County -- a region with a mix of urban residential, small-town suburban, and rural properties. Stearns County's geology includes areas of glacial drift over granite bedrock formations known to produce radon. Homes throughout the St. Cloud area, from older downtown neighborhoods to newer construction in Sartell and Waite Park, can have elevated radon regardless of age or foundation type.
Many central Minnesota homeowners assume radon is primarily a metro-area issue. It isn't. The Minnesota Department of Health's radon testing data shows elevated levels throughout greater Minnesota, not just the Twin Cities. Approximately 2 in 5 MN homes statewide exceed the EPA action level of 4 pCi/L -- a statistic that applies equally to Stearns County as to Hennepin or Wright. St. Cloud State University students living in off-campus basement apartments face the same radon exposure risk as homeowners.
Radon Stoppers, LLC is based in Monticello, approximately 45 miles southeast of St. Cloud -- close enough to schedule efficiently, experienced enough to handle the varied foundation types common in central Minnesota. We're NRPP-certified, MDH-licensed, and back all installations with a 5-year written warranty. Call 763-222-9562 for a free estimate.
Radon Mitigation FAQs for St. Cloud
Does Stearns County have elevated radon risk?
Yes. Stearns County, where St. Cloud is located, is in central Minnesota -- a region the EPA classifies as high-radon. The area has geology including glacial drift over bedrock formations that generate radon. The Minnesota Department of Health estimates about 2 in 5 MN homes statewide test above the EPA action level of 4 pCi/L, and Stearns County homes are included in that risk profile.

Should college renters in St. Cloud worry about radon?
Basement apartments and older rental properties near St. Cloud State University and throughout the city can have elevated radon. Radon exposure is cumulative -- time spent in a high-radon space increases lung cancer risk. Minnesota doesn't currently require landlords to test or disclose radon levels, so renters often have no way of knowing. If you're a tenant, you can purchase a short-term radon test kit at most hardware stores. If you're a landlord, Radon Stoppers can assess and mitigate your rental property.
