What these figures count
Only 9 tests were reported to CDC for Lincoln 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).
Lincoln County, Compared
Lincoln County radon figures, compared
Calculated by Radon411More than half: 63.6% of the 33 radon tests reported to CDC for Lincoln County in 2021 read at least 4 pCi/L. That places it 4th of 62 Kansas counties with 30 or more tests for the same period. That is 31.8 points above the 31.8% pooled from 96 Kansas counties.
The newest figure, in 2022, counts only 9 tests (22.2% at or above 4 pCi/L), too few to compare, so this reading uses the 33-test figure.
The median result, 4.5 pCi/L, sits above EPA's 4 pCi/L action level, and the top reported result was 14.2 pCi/L. The rest split 9.1% under 2 pCi/L and 27.3% from 2 to 4 (Kansas: 45.3% and 22.9%). Zone 1 on EPA's map (predicted average above 4 pCi/L) and a 63.6% share point the same way here.
No bordering county with a figure for the same period reported a higher share; the closest is Russell County at 56.3%, the lowest Ottawa County at 31.7%. Statewide for the same period, Norton County reported the highest share (93.8%) and Doniphan County the lowest (0.0%).
The busiest year on file was 2021, with 33 tests reported; the quietest, 2016, had 6.
Nationally, every county with a figure for the same period pools to 24.4%; Lincoln County sits 39.2 points above it.

The ground under Lincoln County
PredictedUSGS's geologic map puts all of Lincoln County's mapped land in one class: high radon potential. All of it lies in the area the map calls Smoky Hills, 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 |
|---|---|---|---|---|
| Smoky Hills | Cretaceous marine sandstone, shale, and siltstone covered by discontinuous loess deposits. | High | 12 | 100% |
