2023: 0.0%. Across these years the share ran from 0.0% to 50.0%. Each column counts radon tests reported to CDC that year, not homes.
Only 9 tests were reported to CDC for Hooker 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.

Hooker County, Compared
Hooker County's 30 reported tests in 2018 had a middle value of 1.3 pCi/L and a maximum of 5.4 pCi/L, and 20.0% reached 4 pCi/L. Nebraska as a whole (85 Nebraska counties, pooled) comes to 44.5%: 24.5 points higher than here.
The newest figure, in 2023, counts only 9 tests (0.0% at or above 4 pCi/L), too few to compare, so this reading uses the 30-test figure.
Among its state's counties it ranks 70th of 73 Nebraska counties with 30 or more tests for the same period. Statewide for the same period, Colfax County reported the highest share (74.1%) and Cherry County the lowest (10.0%).
Below the action level, 24 tests (80.0%) came in under 2 pCi/L, against 30.7% statewide, and 0 tests (0.0%) fell between 2 and 4, against 24.8% statewide. The busiest year on file was 2018, with 30 tests reported; the quietest, 2019, had 6.
EPA's 1993 zone map puts Hooker County in Zone 3, a predicted county average under 2 pCi/L. USGS geology rates 100% of the county's land low radon potential.
Cherry County, the one bordering county with a figure for the same period, reported 10.0%.
Pooled shares: Radon411's sum of CDC's county counts for one period.
Hooker County, Geology
USGS's geologic map puts all of Hooker County's mapped land in one class: low radon potential. All of it lies in the area the map calls Sand Hills, to which USGS gives a radon index of 8, in the low band (5 to 8).
| Area | The rock, in USGS's words | Potential | Radon index | Share of land |
|---|---|---|---|---|
| Sand Hills | Quaternary windblown sand. | Low | 8 | 100% |

Across Nebraska 40.9% of the land is rated high; none of Hooker County's is. Of the 5 counties that border it, 1 has more moderate-potential ground, Cherry County the most at 1.5%.
The map rates the ground, not the air in any home.
