What these figures count
Only 3 tests were reported to CDC for Logan 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: 2005 to 2021 (every CDC figure on file).
Logan County, Compared
Logan County radon figures, compared
Calculated by Radon411CDC's largest figure for Logan County rests on 12 tests in 2019, 0 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 3.5 pCi/L, with a middle value of 2.0 pCi/L.
Of the counties bordering it, 2 have a figure over the 2008 to 2017 laboratory totals: Custer County reported the largest share at or above 4 pCi/L, 52.3%, and Lincoln County the smallest, 27.0%. Farther out, Dawson County (59 miles away) at 42.7%, Brown County (66 miles away) at 41.9% and Keith County (66 miles away) at 55.0% have figures too. Pooled across 93 Nebraska counties, 58.5% of reported tests reached that level; across every county in the country with a figure, 35.7%.
Statewide for the same period, Clay County reported the highest share (85.1%) and Cherry County the lowest (13.3%). EPA's 1993 map puts Logan County in Zone 3, its lowest label: a predicted county average under 2 pCi/L. USGS geology rates 66% of the county's land low radon potential.

Logan County, Geology
The ground under Logan County
PredictedUSGS's geologic map splits Logan County: 66.4% of its land is low radon potential and 33.6% moderate. The map puts 66.4% of Logan County in the area it calls Sand Hills and 33.6% in Loess over Tertiary sediments. USGS gives the first a radon index of 8, in the low band (5 to 8), and the second 11, in the moderate band (9 to 11).
| Area | The rock, in USGS's words | Potential | Radon index | Share of land |
|---|---|---|---|---|
| Sand Hills | Quaternary windblown sand. | Low | 8 | 66.4% |
| Loess over Tertiary sediments | Tertiary bedrock covered by varying thicknesses of loess. | Moderate | 11 | 33.6% |
