Meeker County, Compared
Meeker County radon figures, compared
Calculated by Radon411In Meeker County, about 5 in 10 reported tests in 2023 (29 of 59) were at or above EPA's action level. Against the national pool of 33.4%, the gap is 15.8 points higher. Across 86 Minnesota counties pooled together, 34.6% of tests reached that level, so Meeker County runs 14.6 points above its state.
Of 5 neighbours with a figure, 3 reported a larger share at or above 4 pCi/L and 2 a smaller one; the spread is 42.4% (Wright County) to 75.7% (Renville County). By share, Meeker County is 24th of 62 Minnesota counties with 30 or more tests for the same period.
Year by year, 2014 opened at 63.2% and 2023 closed at 49.2% (down 14.0 points), with 2021 the high at 68.4%. Half the tests came in under 3.9 pCi/L and half over it; the single highest reached 20.9 pCi/L. Below the action level, 8 tests (13.6%) came in under 2 pCi/L, against 36.6% statewide, and 22 tests (37.3%) fell between 2 and 4, against 28.9% statewide.
Zone 1 on EPA's map (predicted average above 4 pCi/L) and a 49.2% share point the same way here. USGS geology rates 100% of the county's land high radon potential.
The busiest year on file was 2014, with 106 tests reported; the quietest, 2018, had 38.

- 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.

| Area | The rock, in USGS's words | Potential | Radon index | Share of land |
|---|---|---|---|---|
| Central Lowland-Till Prairie | Silty and clayey till derived from shale and sandstone. | High | 14 | 98.5% |
| Central Lowland-Western Lake Section | Sandy calcareous till derived from carbonate rocks. | High | 14 | 1.5% |
