What these figures count
Only 5 tests were reported to CDC for Mineral 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).
Mineral County, Compared
Mineral County radon figures, compared
Calculated by Radon411CDC's largest figure for Mineral County rests on 28 tests in 2020, 5 of them at or above 4 pCi/L, so each test moves its share by 3.6 points and no rank or comparison is drawn from it. Results reached as high as 7.5 pCi/L, with a middle value of 2.1 pCi/L.
Of the counties bordering it, 2 have a figure over the 2008 to 2017 laboratory totals: Rio Grande County reported the largest share at or above 4 pCi/L, 37.5%, and Archuleta County the smallest, 31.2%. Farther out, La Plata County (57 miles away) at 46.0%, Ouray County (57 miles away) at 53.3% and Alamosa County (63 miles away) at 26.6% have figures too. Pooled across 63 Colorado counties, 47.0% of reported tests reached that level; across every county in the country with a figure, 35.7%.
Statewide for the same period, Kit Carson County reported the highest share (71.4%) and Alamosa County the lowest (26.6%). EPA's 1993 map puts Mineral County in Zone 2, its middle label: a predicted county average between 2 and 4 pCi/L. USGS geology rates 100% of the county's land moderate radon potential.
Pooled shares: Radon411's sum of CDC's county counts for one period.

Tests behind these figures
80 tests
- CDPHE says these data do not give actual radon levels in homes that have not been tested.
- When possible, only tests conducted before a mitigation system was installed are used.
- Some counties have very small numbers of test results, and their summaries may be less representative.
- These figures describe tests reported to Colorado CDPHE in this area. They count a different set of tests than CDC's figures and are not a reading of any one home.
Measured: Colorado CDPHE data, 2005-2025.
Mineral County, Geology
The ground under Mineral County
PredictedUSGS's geologic map puts all of Mineral County's mapped land in one class: moderate radon potential. 99.2% of it lies in the area the map calls San Juan Volcanic field, to which USGS gives a radon index of 11, in the moderate band (9 to 11).
| Area | The rock, in USGS's words | Potential | Radon index | Share of land |
|---|---|---|---|---|
| San Juan Volcanic field | Volcanic rocks, rhyolite, tuff, basalt | Moderate | 11 | 99.2% |
| San Juan Basin | Mesozoic marine and non-marine sedimentary rocks including sandstone, siltstone, shale, minor limestone. | Moderate | 11 | 0.8% |

Mineral County beside the ground around it
Across Colorado 74.8% of the land is rated high; none of Mineral County's is. Of the 4 counties that border it, 1 has more high-potential ground, Saguache County the most at 17.0%.
