What these figures count
Only 1 test was reported to CDC for Hayes 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).
Hayes County, Compared
Hayes County radon figures, compared
Calculated by Radon411CDC's largest figure for Hayes County rests on 18 tests in 2015, 12 of them at or above 4 pCi/L, so each test moves its share by 5.6 points and no rank or comparison is drawn from it. Results reached as high as 7.3 pCi/L, with a middle value of 5.3 pCi/L.
Of the counties bordering it, 5 have a figure over the 2008 to 2017 laboratory totals: Chase County reported the largest share at or above 4 pCi/L, 68.2%, and Lincoln County the smallest, 27.0%, with Frontier County at 53.5%, Hitchcock County at 51.6% and Perkins County at 50.0% between. Farther out, Red Willow County (39 miles away) at 61.0%, Keith County (56 miles away) at 55.0% and Gosper County (65 miles away) at 69.0% 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 Hayes County in Zone 1, the map's highest label: a predicted county average above 4 pCi/L. USGS geology rates 82% of the county's land high radon potential.

The ground under Hayes County
PredictedMost of the ground under Hayes County is one class on USGS's geologic map: 82.3% of its land is high radon potential, with 1.5% moderate and 16.2% low. The map puts 82.3% of Hayes County in the area it calls Loess over K-T and 16.2% in Sand Hills, with one smaller area beside them. 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 |
|---|---|---|---|---|
| Loess over K-T | Loess-mantled Tertiary and Cretaceous bedrock. | High | 13 | 82.3% |
| Sand Hills | Quaternary windblown sand. | Low | 8 | 16.2% |
| Tertiary Rocks | Tertiary sandstone, siltstone, and volcanic ash. | Moderate | 11 | 1.5% |

Hayes County, Cities and towns
Cities and towns in Hayes County
About 821 people live in Hayes County by the Census Bureau's estimate for July 1, 2025, 27 fewer than in 2020 (−3.2%). Spread over its land, that is 1.2 people to the square mile. Palisade, the largest place on its list (277 residents in all), extends beyond Hayes County, so no share of the total is worked out for it. CDC's 18 reported tests for 2015 work out to 21.9 per 1,000 residents (2025 estimate), close to Nebraska's 30.4.
From Palisade to Hamlet, CDC publishes no figure by town: each reads Hayes County's.
| Place | Residents | Since 2020 | Share of residents |
|---|---|---|---|
| Palisadeextends beyond Hayes County | 277 | −5.1% | Counted whole |
| Hayes Center | 218 | −2.7% | 26.6% |

3 incorporated places, as listed in the U.S. Census Bureau’s 2020 place reference files. Residents: U.S. Census Bureau population estimates for July 1, 2025 (Vintage 2025). A place that extends beyond Hayes County is counted whole, so it has no share.
