Sources
Official sources for the Minneapolis radon test kit guide
Claims here trace to EPA, MDH, or Hennepin County. Zones come from EPA’s June 2024 Map of Radon Zones data. Testing steps, the two-test chart, monitor limits, and the “more than three times the U.S. level” statement come from MDH and the testing page. Sale rules come from the Awareness Act page.
This guide does not republish block-level numbers, name companies, or invent licenses. If a sentence and its source disagree, the source wins.
Minnesota
- MDH radon page: Statewide context, the smoking-and-radon table, and why a closed heating season in your home matters.
- 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 construction: If your Minneapolis home was built new since 2009, it should have a vent pipe, not a fan. Test it anyway.
- 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.
