What these figures count
Only 12 tests were reported to CDC for Hodgeman County over 2021, 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: 2021. Measured data period: 2016 to 2021 (every CDC figure on file).
Hodgeman County, Compared
Hodgeman County radon figures, compared
Calculated by Radon411CDC's largest figure for Hodgeman County rests on 12 tests in 2021, 6 of them at or above 4 pCi/L, so each test moves its share by 8.3 points and no rank or comparison is drawn from it. Results reached as high as 5.6 pCi/L, with a middle value of 4.6 pCi/L.
Of the counties bordering it, 3 have a figure in 2019: Pawnee County reported the largest share at or above 4 pCi/L, 66.7%, and Finney County the smallest, 30.1%, with Ford County at 42.4% between. Farther out, Scott County (61 miles away) at 61.5%, Ellis County (65 miles away) at 41.6% and Barton County (68 miles away) at 24.6% 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 Hodgeman 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.

Hodgeman County, Geology
The ground under Hodgeman County
PredictedUSGS's geologic map puts all of Hodgeman County's mapped land in one class: high radon potential. The map puts 64.0% of Hodgeman County in the area it calls Smoky Hills and 36.0% in Ogallala Formation. USGS gives both 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 | 64.0% |
| Ogallala Formation | Tertiary sandstone, in part covered by windblown eolian sand and loess deposits. | High | 12 | 36.0% |
