What these figures count
Only 10 tests were reported to CDC for Boone 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).
Boone County, Compared
Boone County radon figures, compared
Calculated by Radon411More than half: 65.4% of the 321 radon tests reported to CDC for Boone County in 2017 read at least 4 pCi/L. That places it 15th of 74 Nebraska counties with 30 or more tests for the same period. That is 17.7 points above the 47.7% pooled from 92 Nebraska counties.
The newest figure, in 2023, counts only 10 tests (80.0% at or above 4 pCi/L), too few to compare, so this reading uses the 321-test figure.
The median result, 6.1 pCi/L, sits above EPA's 4 pCi/L action level, and the top reported result was 25.7 pCi/L. The rest split 18.7% under 2 pCi/L and 15.9% from 2 to 4 (Nebraska: 25.6% and 26.7%). Zone 1 on EPA's map (predicted average above 4 pCi/L) and a 65.4% share point the same way here.
No bordering county with a figure for the same period reported a higher share; the closest is Antelope County at 58.5%, the lowest Platte County at 53.3%. 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 321 tests reported; the quietest, 2023, had 10.
Over 8 years of annual figures the share fell 22.5 points, from 62.5% in 2014 to 40.0% in 2021; its peak was 75.5% in 2015. Nationally, every county with a figure for the same period pools to 31.7%; Boone County sits 33.7 points above it.

The ground under Boone County
PredictedMost of the ground under Boone County is one class on USGS's geologic map: 92.7% of its land is high radon potential, with 7.3% low. The map puts 92.7% of Boone County in the area it calls Pre-Wisconsin glacial deposits and 7.3% in Sand Hills. USGS gives the first a radon index of 13, in the high band (12 to 17), and the second 8, in the low band (5 to 8).
| Area | The rock, in USGS's words | Potential | Radon index | Share of land |
|---|---|---|---|---|
| Pre-Wisconsin glacial deposits | Loess-mantled glacial drift. | High | 13 | 92.7% |
| Sand Hills | Quaternary windblown sand. | Low | 8 | 7.3% |
