What these figures count
Only 4 tests were reported to CDC for Kittson County over 2023, and tests are often run on homes being sold or already suspected of a problem: so few describe neither the county nor this house.
Measured: CDC tracking data. Figure above: 2023. Measured data period: 2005 to 2023 (every CDC figure on file).
Kittson County, Compared
Kittson County radon figures, compared
Calculated by Radon411In Kittson County, about 4 in 10 reported tests over the 2006 to 2015 laboratory totals (12 of 34) were at or above EPA's action level. Against the national pool of 36.3%, the gap is 1.0 points lower. Across 87 Minnesota counties pooled together, 45.0% of tests reached that level, so Kittson County runs 9.7 points below its state.
The newest figure, in 2023, counts only 4 tests (25.0% at or above 4 pCi/L), too few to compare, so this reading uses the 34-test figure.
Of 3 neighbours with a figure, 2 reported a larger share at or above 4 pCi/L and 1 a smaller one; the spread is 25.6% (Roseau County) to 78.1% (Pembina County, ND). By share, Kittson County is 69th of 87 Minnesota counties with 30 or more tests for the same period.
Half the tests came in under 2.6 pCi/L and half over it; the single highest reached 30.9 pCi/L. Below the action level, 12 tests (35.3%) came in under 2 pCi/L, against 26.2% statewide, and 10 tests (29.4%) fell between 2 and 4, against 28.8% statewide.
Zone 1 on EPA's map (predicted average above 4 pCi/L) and a 35.3% share point the same way here. USGS geology rates 89% of the county's land high radon potential.
The busiest year on file was 2014, with 12 tests reported; the quietest, 2021, had 2.
Pooled shares: Radon411's sum of CDC's county counts for one period.

Tests behind these figures
4 properties tested a year on average
- MDH says these data do not include all of the radon tests conducted in Minnesota.
- Post-mitigation tests are excluded from the averages and the median; the percentages use each property's highest test.
- Each home is unique and can have very different results than a neighbor's home; the only way to know is to test.
- These figures describe tests reported to the Minnesota Department of Health in this area. They count a different set of tests than CDC's figures and are not a reading of any one home.

Kittson County, Geology
The ground under Kittson County
PredictedMost of the ground under Kittson County is one class on USGS's geologic map: 89.1% of its land is high radon potential, with 10.8% moderate. The map puts 89.0% of Kittson County in the area it calls Lake Agassiz Plain and 10.8% in Lake Agassiz Plain/Central Lowland-Western Lake Section. USGS gives the first a radon index of 15, in the high band (12 to 17), and the second 10, in the moderate band (9 to 11).
| Area | The rock, in USGS's words | Potential | Radon index | Share of land |
|---|---|---|---|---|
| Lake Agassiz Plain | Silt and clay deposits of Glacial Lake Agassiz derived from Cretaceous shales containing higher than average amounts of uranium. | High | 15 | 89.0% |
| Lake Agassiz Plain/Central Lowland-Western Lake Section | Silty and clayey glacial deposits and lake deposits. | Moderate | 10 | 10.8% |
