What these figures count
Only 3 tests were reported to CDC for Perkins County over 2023, 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: 2023. Measured data period: 2005 to 2023 (every CDC figure on file).
Perkins County, Compared
Perkins County radon figures, compared
Calculated by Radon411More than half: 52.9% of the 51 radon tests reported to CDC for Perkins County in 2017 read at least 4 pCi/L. That places it 46th of 74 Nebraska counties with 30 or more tests for the same period. That is 5.2 points above the 47.7% pooled from 92 Nebraska counties.
The newest figure, in 2023, counts only 3 tests (100.0% at or above 4 pCi/L), too few to compare, so this reading uses the 51-test figure.
The median result, 4.4 pCi/L, sits above EPA's 4 pCi/L action level, and the top reported result was 12.3 pCi/L. The rest split 11.8% under 2 pCi/L and 35.3% from 2 to 4 (Nebraska: 25.6% and 26.7%). The reported tests do not follow EPA's Zone 2 label for Perkins County (predicted average between 2 and 4 pCi/L): 52.9% of them reached 4 pCi/L, fewer than that label suggests.
2 of its 4 bordering counties with figures ran higher, led by Chase County at 76.5%; Lincoln County reported 18.9%. Statewide for the same period, Webster County reported the highest share (84.6%) and Cherry County the lowest (15.4%).
The busiest year on file was 2017, with 51 tests reported; the quietest, 2023, had 3.
Over 3 years of annual figures the share fell 30.3 points, from 63.6% in 2015 to 33.3% in 2019; its peak was 63.6% in 2015. Nationally, every county with a figure for the same period pools to 31.7%; Perkins County sits 21.2 points above it.

The ground under Perkins County
PredictedMost of the ground under Perkins County is one class on USGS's geologic map: 91.2% of its land is moderate radon potential, with 7.2% high and 1.6% low. The map puts 91.2% of Perkins County in the area it calls Tertiary Rocks and 7.2% in Ogallala Formation, with one smaller area beside them. USGS gives the first a radon index of 11, in the moderate band (9 to 11), and the second 12, in the high band (12 to 17).
| Area | The rock, in USGS's words | Potential | Radon index | Share of land |
|---|---|---|---|---|
| Tertiary Rocks | Tertiary sandstone, siltstone, and volcanic ash. | Moderate | 11 | 91.2% |
| Ogallala Formation | Tertiary sandstone, in part covered by windblown eolian sand and loess deposits. | High | 12 | 7.2% |
| Sand Hills | Quaternary windblown sand. | Low | 8 | 1.6% |
