Why do inspectors recommend radon testing on every Minnesota home?

Inspectors recommend radon testing on every Minnesota home because the state's odds are genuinely bad, roughly two in five homes test above the EPA action level, and because no map, neighbor's result, or house characteristic can substitute for testing the actual home. Radon is a naturally occurring radioactive gas from the breakdown of uranium in soil and bedrock; it's invisible, odorless, and the leading cause of lung cancer among nonsmokers. Minnesota's glacial soils and geology make it a national hot spot: the EPA maps most of the state as Zone 1, its highest-potential category, with the Duluth area's St. Louis County as one of 19 Zone 2 counties, and even Zone 2 homes should be tested, since zones describe regional averages, not individual houses. Radon enters through foundation cracks, sump baskets, slab joints, and utility penetrations, driven by the pressure difference between the soil and the house, which is strongest during our long heating season when homes are sealed tight. That's why new homes, old homes, homes with finished basements, and slab-on-grade homes can all test high, and why identical neighbors often test completely differently. A professional test during your inspection period takes about two days and gives you a real number and, if it's elevated, negotiating leverage, since mitigation is a well-established fix.
