Radon tests reported for Cibola County, 2008 to 2017, laboratory
CDC holds 13 reported tests for Cibola County over the 2008 to 2017 laboratory totals, with a median of 5.5 pCi/L: too few to describe a county (Radon411 reads a share from 30 tests up). Cibola County beside the counties around it is how this page reads it.
What these figures count
Only 13 tests were reported to CDC for Cibola County over 2008 to 2017 (laboratory totals), 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: 2008 to 2017, laboratory. Measured data period: 2005 to 2017 (every CDC figure on file).
Cibola County, Compared
Cibola County radon figures, compared
Calculated by Radon411CDC's largest figure for Cibola County rests on 20 tests over the 2005 to 2014 laboratory totals, 8 of them at or above 4 pCi/L, so each test moves its share by 5.0 points and no rank or comparison is drawn from it. Results reached as high as 16.9 pCi/L, with a middle value of 3.5 pCi/L.
Of the counties bordering it, 3 have a figure over the 2006 to 2015 laboratory totals: McKinley County reported the largest share at or above 4 pCi/L, 41.9%, and Sandoval County the smallest, 24.7%, with Bernalillo County at 25.2% between. Farther out, San Juan County (112 miles away) at 30.0%, Los Alamos County (116 miles away) at 38.3% and Santa Fe County (122 miles away) at 32.5% have figures too. Pooled across 30 New Mexico counties, 30.3% of reported tests reached that level; across every county in the country with a figure, 36.3%.
Statewide for the same period, Taos County reported the highest share (71.9%) and Otero County the lowest (10.7%). EPA's 1993 map puts Cibola County in Zone 2, its middle label: a predicted county average between 2 and 4 pCi/L. USGS geology rates 79% of the county's land moderate radon potential.

The ground under Cibola County
PredictedMost of the ground under Cibola County is one class on USGS's geologic map: 78.9% of its land is moderate radon potential, with 21.1% high. The map puts 68.4% of Cibola County in the area it calls Southern Colorado Plateau and 21.1% in Grants Uranium Belt, with 2 smaller areas beside them. USGS gives the first a radon index of 10, 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 |
|---|---|---|---|---|
| Southern Colorado Plateau | Cretaceous marine sandstone, shale. | Moderate | 10 | 68.4% |
| Grants Uranium Belt | Upper Creataceous marine shales and uranium-bearing Jurassic fluvial sandstones of the Grants uranium belt. | High | 12 | 21.1% |
| San Juan Basin | Mesozoic marine and non-marine sedimentary rocks including sandstone, siltstone, shale, minor limestone. | Moderate | 10 | 6.4% |
| Colorado Plateau | Jurassic-Triassic nonmarine sandstones and shales. | Moderate | 11 | 4.1% |
