What these figures count
These are the 49 tests reported to CDC for Juab County over 2023, many from homes being sold or already suspected of a problem: they describe the county's reported tests, not this house.
Measured: CDC tracking data. Figure above: 2023. Measured data period: 2005 to 2023 (every CDC figure on file).
Juab County, Compared
Juab County radon figures, compared
Calculated by Radon411More than half: 63.3% of the 49 radon tests reported to CDC for Juab County in 2023 read at least 4 pCi/L. That places it 2nd of 22 Utah counties with 30 or more tests for the same period. That is 27.2 points above the 36.1% pooled from 29 Utah counties.
The median result, 5.0 pCi/L, sits above EPA's 4 pCi/L action level, and the top reported result was 45.1 pCi/L. The rest split 16.3% under 2 pCi/L and 20.4% from 2 to 4 (Utah: 35.4% and 28.5%). The reported tests do not follow EPA's Zone 2 label for Juab County (predicted average between 2 and 4 pCi/L): 63.3% of them reached 4 pCi/L, fewer than that label suggests.
No bordering county with a figure for the same period reported a higher share; the closest is Sanpete County at 60.0%, the lowest Utah County at 40.6%. Statewide for the same period, Beaver County reported the highest share (66.7%) and Washington County the lowest (9.9%).
The busiest year on file was 2022, with 75 tests reported; the quietest, 2019, had 2.
Nationally, every county with a figure for the same period pools to 33.4%; Juab County sits 29.9 points above it. CDC also counts 7 tests taken after mitigation in Juab County for the same period: tests in homes where a fix was already in.

The ground under Juab County
PredictedMost of the ground under Juab County is one class on USGS's geologic map: 81.2% of its land is moderate radon potential, with 18.8% high. The map puts 79.5% of Juab County in the area it calls Basin and Range and 18.8% in Northern High Plateau, with one smaller area beside them. USGS gives the first a radon index of 11, in the moderate band (9 to 11), and the second 12, in the high band (12 to 17).
| Area | The rock, in USGS's words | Potential | Radon index | Share of land |
|---|---|---|---|---|
| Basin and Range | Quaternary sedimentary and igneous rocks. | Moderate | 11 | 79.5% |
| Northern High Plateau | Tertiary and Cretaceous sedimentary rocks. | High | 12 | 18.8% |
| Uinta Mountains | Cretaceous marine shales with Tertiary continental sedimentary rocks on the southern flank. | Moderate | 10 | 1.6% |

Juab County, Cities and towns
Cities and towns in Juab County
Juab County is growing: the Census Bureau puts it at 13,567 residents on July 1, 2025, up 14.8% from 11,821 in 2020. Spread over its land, that is 4.0 people to the square mile. Santaquin, the largest place on its list (18,989 residents in all), extends beyond Juab County, so no share of the total is worked out for it. Reported testing is thin here: 49 tests over 2023, or 3.6 for every 1,000 residents (2025 estimate), where Utah as a whole comes to 7.7.
From Santaquin to Eureka, CDC publishes no figure by town: each reads Juab County's.
