Only 2 tests were reported to CDC for Kearny 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).
Kearny County, Compared
Kearny County radon figures, compared
Calculated by Radon411CDC's largest figure for Kearny County rests on 16 tests in 2018, 3 of them at or above 4 pCi/L, so each test moves its share by 6.3 points and no rank or comparison is drawn from it. Results reached as high as 7.3 pCi/L, with a middle value of 1.3 pCi/L.
Of the counties bordering it, 2 have a figure in 2019: Scott County reported the largest share at or above 4 pCi/L, 61.5%, and Finney County the smallest, 30.1%. Farther out, Seward County (61 miles away) at 52.2%, Ford County (81 miles away) at 42.4% and Thomas County (94 miles away) at 45.5% 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 Kearny County in Zone 1, the map's highest label: a predicted county average above 4 pCi/L. USGS geology rates 69% of the county's land high radon potential.

Kearny County, Geology
The ground under Kearny County
PredictedUSGS's geologic map splits Kearny County: 68.7% of its land is high radon potential and 31.3% moderate. The map puts 68.0% of Kearny County in the area it calls Ogallala Formation and 31.3% in Arkansas River Lowlands, with one smaller area beside them. USGS gives the first a radon index of 12, 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 |
|---|---|---|---|---|
| Ogallala Formation | Tertiary sandstone, in part covered by windblown eolian sand and loess deposits. | High | 12 | 68.0% |
| Arkansas River Lowlands | Dune sands and alluvium. | Moderate | 10 | 31.3% |
| High Plains | Quaternary deposits and Cretaceous marine shales that locally have a high radiometric signature. | High | 12 | 0.8% |
