What these figures count
Only 1 test was reported to CDC for Stevens County over 2022, 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: 2022. Measured data period: 2016 to 2022 (every CDC figure on file).
Stevens County, Compared
Stevens County radon figures, compared
Calculated by Radon411CDC's largest figure for Stevens County rests on 25 tests in 2019, 9 of them at or above 4 pCi/L, so each test moves its share by 4.0 points and no rank or comparison is drawn from it. Results reached as high as 11.9 pCi/L, with a middle value of 2.6 pCi/L.
Seward County, the one bordering county with a figure in 2019, reported 52.2% of its tests at or above 4 pCi/L. Farther out, Finney County (67 miles away) at 30.1%, Ford County (86 miles away) at 42.4% and Scott County (92 miles away) at 61.5% have figures too. Pooled across 102 Kansas counties, 33.7% of reported tests reached that level; across every county in the country with a figure, 29.0%.
Statewide for the same period, Jewell County reported the highest share (71.9%) and Reno County the lowest (20.8%). EPA's 1993 map puts Stevens County in Zone 2, its middle label: a predicted county average between 2 and 4 pCi/L. USGS geology rates 100% of the county's land moderate radon potential.

PredictedMost of the ground under Stevens County is one class on USGS's geologic map: 99.9% of its land is moderate radon potential, with 0.1% high. All of it lies in the area the map calls Cimmaron River Valley, to which USGS gives a radon index of 10, in the moderate band (9 to 11).
| Area | The rock, in USGS's words | Potential | Radon index | Share of land |
|---|---|---|---|---|
| Cimmaron River Valley | Tertiary and Quaternary sandstone, siltstone, shale, and alluvium overlain by eolian sand and loess. | Moderate | 10 | 99.9% |
