What's radon like where you live?
Enter your address or pick your county to see the Minnesota Department of Health's test statistics for your area: how many local homes tested at or above the 4 pCi/L action level, and what that means in plain English. Your lookup is anonymous and never stored.
Your address is used once to find your county, then discarded. It is never stored.

Frequently asked questions
- Where do these county numbers come from?
- Directly from the Minnesota Department of Health's published radon test statistics, which we fetch on a schedule and republish with the date we last checked them. If our copy and MDH's page ever disagree, MDH's page controls.
- My county looks lower than others. Does that mean my home is safe?
- No. County statistics describe the homes that happened to be tested, not yours. Two houses next door to each other can have completely different radon levels. Every Minnesota county has high radon potential, and the only way to know your home is to test it.
- What does 4 pCi/L mean?
- Picocuries per liter is the unit for radon concentration in air. The EPA and MDH set 4 pCi/L as the action level: at or above it, fix the home. There is no known safe level, and the EPA suggests considering mitigation even between 2 and 4.
- Do you store the address I look up?
- No. The address is sent to the U.S. Census Bureau's public geocoder only to find the county, we return that county's statistics, and the address is discarded. It is never written to a database or a log we keep.
