What these figures count
These are the 207 tests reported to CDC for Morgan 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).
Morgan County, Compared
Morgan County radon figures, compared
Calculated by Radon411More than half: 59.4% of the 207 radon tests reported to CDC for Morgan County in 2023 read at least 4 pCi/L. That places it 4th of 22 Utah counties with 30 or more tests for the same period. That is 23.3 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 68.6 pCi/L. The rest split 14.0% under 2 pCi/L and 26.6% from 2 to 4 (Utah: 35.4% and 28.5%). The reported tests do not follow EPA's Zone 2 label for Morgan County (predicted average between 2 and 4 pCi/L): 59.4% 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 Salt Lake County at 33.1%, the lowest Davis County at 28.4%. 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 2023, with 207 tests reported; the quietest, 2019, had 14.
Over 6 years of annual figures the share fell 12.5 points, from 71.9% in 2015 to 59.4% in 2023; its peak was 71.9% in 2015. Nationally, every county with a figure for the same period pools to 33.4%; Morgan County sits 26.0 points above it. CDC also counts 30 tests taken after mitigation in Morgan County for the same period: tests in homes where a fix was already in.

The ground under Morgan County
PredictedMost of the ground under Morgan County is one class on USGS's geologic map: 99.7% of its land is high radon potential, with 0.3% moderate. The map puts 66.4% of Morgan County in the area it calls Northern Rocky Mountains and 33.2% in Wasatch Range. USGS gives the first a radon index of 13 and the second 14, both in the high band (12 to 17).
| Area | The rock, in USGS's words | Potential | Radon index | Share of land |
|---|---|---|---|---|
| Northern Rocky Mountains | Tertiary sandstone, mudstone, limestone. | High | 13 | 66.4% |
| Wasatch Range | Precambrian granite and gneiss and Tertiary igneous rocks that have relatively low uranium concentrations. | High | 14 | 33.2% |
