What these figures count
Only 27 tests were reported to CDC for Wayne 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).
Wayne County, Compared
Wayne County radon figures, compared
Calculated by Radon411CDC's largest figure for Wayne County rests on 27 tests in 2023, 19 of them at or above 4 pCi/L, so each test moves its share by 3.7 points and no rank or comparison is drawn from it. Results reached as high as 51.0 pCi/L, with a middle value of 5.5 pCi/L.
Of the counties bordering it, 3 have a figure in 2023: Sevier County reported the largest share at or above 4 pCi/L, 57.4%, and Grand County the smallest, 23.9%, with Emery County at 38.5% between. Farther out, Sanpete County (81 miles away) at 60.0%, Carbon County (93 miles away) at 23.2% and Beaver County (127 miles away) at 66.7% have figures too. Pooled across 29 Utah counties, 36.1% of reported tests reached that level; across every county in the country with a figure, 33.4%.
Statewide for the same period, Beaver County reported the highest share (66.7%) and Washington County the lowest (9.9%). EPA's 1993 map puts Wayne County in Zone 2, its middle label: a predicted county average between 2 and 4 pCi/L. USGS geology rates 86% of the county's land moderate radon potential.

The ground under Wayne County
PredictedMost of the ground under Wayne County is one class on USGS's geologic map: 85.7% of its land is moderate radon potential, with 14.3% high. The map puts 85.7% of Wayne County in the area it calls Colorado Plateau and 14.3% in High Plateau. USGS gives the first a radon index of 9, in the moderate band (9 to 11), and the second 13, in the high band (12 to 17).
| Area | The rock, in USGS's words | Potential | Radon index | Share of land |
|---|---|---|---|---|
| Colorado Plateau | Paleozoic and Mesozoic sandstone, shale, limestone. | Moderate | 9 | 85.7% |
| High Plateau | Tertiary volcanic and volcaniclastic rocks. | High | 13 | 14.3% |
