Mitchell County, Compared
Mitchell County radon figures, compared
Calculated by Radon411More than half: 57.4% of the 47 radon tests reported to CDC for Mitchell County in 2022 read at least 4 pCi/L. That places it 1st of 38 Kansas counties with 30 or more tests for the same period. That is 25.4 points above the 32.0% pooled from 96 Kansas counties.
The median result, 6.2 pCi/L, sits above EPA's 4 pCi/L action level, and the top reported result was 25.5 pCi/L. The rest split 19.1% under 2 pCi/L and 23.4% from 2 to 4 (Kansas: 45.8% and 22.1%). Zone 1 on EPA's map (predicted average above 4 pCi/L) and a 57.4% share point the same way here.
Cloud County, the one bordering county with a figure for the same period, reported 54.6%. Statewide for the same period, Clay County reported the highest share (55.8%) and Crawford County the lowest (5.9%).
The busiest year on file was 2021, with 177 tests reported; the quietest, 2016, had 37.
Over 7 years of annual figures the share fell 21.0 points, from 78.4% in 2016 to 57.4% in 2022; its peak was 78.4% in 2016. Nationally, every county with a figure for the same period pools to 23.9%; Mitchell County sits 33.5 points above it. CDC also counts 10 tests taken after mitigation in Mitchell County for the same period: tests in homes where a fix was already in.

| 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% |
