Minneapolis radon test kit, on one page
Reviewed for accuracy against EPA and Minnesota Department of Health guidance on September 23, 2026.
Test your Minneapolis home. Hennepin County is EPA Zone 1, and Anoka County is Zone 2. MDH says Minnesota’s average is more than three times the national level, and more than two in five tests reach a level it calls a significant risk. None of that is your number.
Use a short-term kit for 2 to 7 days on the lowest level you use, at least 20 inches off the floor, with your home closed. Heating season is the better time. Wait out a windstorm.
Take MDH’s second test before you mitigate. A store-bought monitor is a diary, not your decision. At 4.0 pCi/L or higher on the follow-up, hire an MDH-licensed mitigator. If your home was built new since 2009, it should have a passive vent, not a fan. Test it anyway.

Check the kit, then pick the room
Read the instructions and the expiration date. Test the lowest level you regularly use. If you spend more than about 10 hours a week in the basement, test there. If you are buying, test the lowest level of your Minneapolis home.

Set it at least 20 inches off the floor
Prefer breathing height. Keep the kit 1 foot from exterior walls, 3 feet from exterior windows, and away from drafts, kitchens, baths, laundry, fireplaces, and furnaces.

Close your Minneapolis home
Any test under three months needs closed-home conditions. Windows and exterior doors stay shut except when you come and go. Run heating and cooling as you normally do. The heating season is the better time for your short-term test.

Wait out severe weather
If the week is unusually windy or the weather is severe, do not start. MDH says weather changes indoor radon. There is no correction factor to apply afterward.
- 5
Run the short-term test for 2 to 7 days
Follow the device inside that window. Keep your start and stop notes. Mail the kit the way the lab requires, including any analysis fee the instructions mention.

Take the second test MDH asks for
A first result around 0 to 1.9 pCi/L means retest in 2 to 5 years. Around 2 to 7.9, follow with a long-term test. Around 8 or higher, follow with another short-term test. Mitigate at 4 or above on that follow-up. A consumer monitor does not replace it.
