Official sources for the Minneapolis radon test kit guide
Factual claims on this site trace to EPA, the Minnesota Department of Health, or Hennepin County. Zones come from EPA’s Map of Radon Zones data (June 2024) linked from the zone map. Testing steps, the two-test decision chart, consumer-monitor limits, and the “more than three times the U.S. level” and “more than two in five homes” statements come from MDH and the testing page. Sale rules come from the Awareness Act pages. Passive new-home requirements since 2009 come from MDH’s radon-resistant construction page.
This guide does not republish neighborhood averages from the data portal, name mitigation companies, or invent license numbers. If a sentence and the linked page disagree, the official page wins.
Minnesota
- MDH radon in homes — Statewide context, the smoking-and-radon table, and why closed heating seasons matter.
- MDH radon testing — Short-term versus long-term kits, placement, and the two-test decision chart.
- Radon in real estate — Minnesota Radon Awareness Act disclosure rules. Testing is recommended, not required to close.
- MDH licensed providers — Measurement and mitigation professionals licensed by the state. Not a paid directory from this guide.
- Licensing explained — Why an NRPP card alone does not authorize radon work in Minnesota.
- Radon-resistant new homes — Since 2009, new Minnesota homes need passive features, including a vent pipe and not a fan.
- Financial assistance — MDH’s page for help paying for mitigation. Rules live there, not in this guide.
- Radon data portal — County context from MDH. This guide does not copy those charts into neighborhood claims.
Hennepin County
- Hennepin County radon testing — Local kit options, why sealing alone falls short, and the county’s published cost range.
National directories and EPA
- NRPP search — Useful context. The MDH license is still required for work in Minnesota.
- NRSB find a pro — National directory. Same Minnesota rule: state licensure comes first.
- EPA qualified-provider page — How EPA tells you to start with the state program, then the national lists.
- Map of Radon Zones — Hennepin is Zone 1. Anoka is Zone 2. Test either way.
- Citizen’s Guide (PDF) — National testing guide, including why a neighbor’s result is not yours.
- Consumer’s Guide (PDF) — How soil-suction systems work and why caulk is not a standalone fix.
- EPA radon publications — Current index of EPA radon guides.
- Find a mitigator (MDH) — MDH’s mitigation-professional finder and hiring questions, including the warning about very low bids.
