Radon in Minnesota
radon 101: what you need to know
Minnesota & Radon
-
Unique Geology: Radon is a gas omitted from the natural decay of uranium and radium deposits found in rocks, soil, and water in Minnesota.
-
3x the Average: The state's average indoor radon level is 4.2 pCi/L, compared to the national average of just 1.3 pCi/L.
-
2 in 5 Homes: Over 40% of homes statewide test at dangerously high, unsafe levels.
-
72% of Counties: Nearly three-quarters of all Minnesota counties sit in high-risk zones.Â
-
High Risk Factors: Minnesota’s cold climate and the "stack effect" can draw up and trap high levels of radon gas indoors, especially in winter months.
Lung Cancer & Radon
-
#1 Non-Smoker Cause: Radon is the single leading environmental cause of lung cancer deaths among non-smokers.
-
21,000 Annual Deaths: It claims roughly 21,000 lives each year in the United States alone.
-
Every 25 Minutes: One person in the U.S. dies from radon-induced lung cancer every 25 minutes.
-
The Smoking Multiplier: If you smoke and your home has high radon, your cancer risk increases by roughly 10 times.
-
Cumulative Risk:Â The risk increases with both higher concentrations of radon and longer exposure times.
Your Home & Radon
-
Invisible Threat: You can't see, smell or taste radon. Testing is the only way to know your homes level of exposure.
-
Soil To Structure:Â Every home has radon. It enters through the foundation and can build up to dangerous levels inside your home.
-
Any Era, Any Style: Older historic builds, mid-century ramblers, and modern-new construction are all equally vulnerable.
-
Basement Exposure: Lower levels, finished crawlspaces, and split-levels trap the highest concentrations of radon.Â
-
Same Block, Different Levels:Â Homes in the same neighborhood, or even on the same block, can have very different levels of radon.
Radon Testing
-
Never Been Tested: When buying, selling, or you don't know the homes radon level.
-
Retesting Timeline: Every 2 years with a mitigation system, or every 5 years without.
-
Structural Changes:Â Â Following any major home modifications including basement renovations, home additions, upgrading HVAC components, or installing new windows.
-
Winter Advantage: While testing can happen anytime, the heating season provides the most accurate "worst-case scenario"averages.
Radon Monitoring
-
Trusted Technology:Â When possible, use reliable & professional testing methods, like continuous radon monitors (CRM) rather than passive short-term test kits.
-
48 Hour Accuracy: Track hourly fluctuations over a 48 hour period to weed out environmental anomalies.
-
Certified Results:Â Use monitors that record temperature, humidity, and movement to ensure accurate and reliable real estate data.
-
Real Estate Negotiations:Â If levels are high, you may be able to discuss the costs of a mitigation system during your negotiations.
Radon Mitgation
-
The Action Threshold: The EPA strongly suggests a professional mitigation system for any home testing 4.0 pCi/L or higher.
-
Active Soil Depressurization: The most common fix uses a specialized vent pipe and inline fan to pull gas out before it collects in your home.
-
Permanent Reduction: A professionally installed active system safely reduces toxic radon levels below 2.0 pCi/L.
-
Licensing Matters: Minnesota state law dictates that all transactional mitigation must be handled by an MDH-licensed professional.
