What these figures count
Only 2 tests were reported to CDC for Wichita 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).
Wichita County, Compared
Wichita County radon figures, compared
Calculated by Radon411CDC's largest figure for Wichita County rests on 9 tests in 2018, 8 of them at or above 4 pCi/L, so each test moves its share by 11.1 points and no rank or comparison is drawn from it. Results reached as high as 11.1 pCi/L, with a middle value of 6.8 pCi/L.
Scott County, the one bordering county with a figure in 2019, reported 61.5% of its tests at or above 4 pCi/L. Farther out, Finney County (45 miles away) at 30.1%, Thomas County (62 miles away) at 45.5% and Sherman County (63 miles away) at 58.7% 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 Wichita County in Zone 1, the map's highest label: a predicted county average above 4 pCi/L. USGS geology rates 100% of the county's land high radon potential.

The ground under Wichita County
PredictedUSGS's geologic map puts all of Wichita County's mapped land in one class: high radon potential. 99.5% of it lies in the area the map calls Ogallala Formation, to which USGS gives a radon index of 12, in the high band (12 to 17).
| 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 | 99.5% |
| Smoky Hills | Cretaceous marine sandstone, shale, and siltstone covered by discontinuous loess deposits. | High | 12 | 0.5% |
