What these figures count
Only 22 tests were reported to CDC for Dixon 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).
Dixon County, Compared
Dixon County radon figures, compared
Calculated by Radon411More than half: 78.0% of the 327 radon tests reported to CDC for Dixon County in 2017 read at least 4 pCi/L. That places it 2nd of 74 Nebraska counties with 30 or more tests for the same period. That is 30.3 points above the 47.7% pooled from 92 Nebraska counties.
The newest figure, in 2023, counts only 22 tests (72.7% at or above 4 pCi/L), too few to compare, so this reading uses the 327-test figure.
The median result, 7.2 pCi/L, sits above EPA's 4 pCi/L action level, and the top reported result was 64.0 pCi/L. The rest split 11.0% under 2 pCi/L and 11.0% from 2 to 4 (Nebraska: 25.6% and 26.7%). Zone 1 on EPA's map (predicted average above 4 pCi/L) and a 78.0% share point the same way here.
No bordering county with a figure for the same period reported a higher share; the closest is Cedar County at 75.1%, the lowest Wayne County at 53.4%. 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 327 tests reported; the quietest, 2022, had 15.
Over 8 years of annual figures the share held within 2 points, from 63.6% in 2014 to 61.9% in 2021; its peak was 85.5% in 2016. Nationally, every county with a figure for the same period pools to 31.7%; Dixon County sits 46.3 points above it.

Dixon County, Geology
The ground under Dixon County
PredictedUSGS's geologic map puts all of Dixon County's mapped land in one class: high radon potential. All of it lies in the area the map calls Pre-Wisconsin glacial deposits, to which USGS gives a radon index of 13, in the high band (12 to 17).
| Area | The rock, in USGS's words | Potential | Radon index | Share of land |
|---|---|---|---|---|
| Pre-Wisconsin glacial deposits | Loess-mantled glacial drift. | High | 13 | 99.8% |

Dixon County, Cities and towns
Cities and towns in Dixon County
Dixon County's population has barely moved since 2020: 5,602 residents on July 1, 2025 against 5,581 then, by the Census Bureau's estimates. That works out to 12 people per square mile of land. Wakefield, the largest place on its list (1,527 residents in all), extends beyond Dixon County, so no share of the total is worked out for it. Testing is reported here more often than across the state: CDC's 327 reported tests for 2017 come to 58.4 for every 1,000 residents (2025 estimate), against 32.5 for Nebraska.
From Wakefield to Maskell, CDC publishes no figure by town: each reads Dixon County's.
