Radon tests reported for Mora County, 2008 to 2017, laboratory
CDC holds 4 reported tests for Mora County over the 2008 to 2017 laboratory totals, with a median of 3.0 pCi/L: too few to describe a county (Radon411 reads a share from 30 tests up). Mora County beside the counties around it is how this page reads it.
What these figures count
Only 4 tests were reported to CDC for Mora 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).
Mora County, Compared
Mora County radon figures, compared
Calculated by Radon411CDC's largest figure for Mora County rests on 7 tests over the 2006 to 2015 laboratory totals, 3 of them at or above 4 pCi/L, so each test moves its share by 14.3 points and no rank or comparison is drawn from it. Results reached as high as 13.8 pCi/L, with a middle value of 3.4 pCi/L.
Of the counties bordering it, 3 have a figure over the 2006 to 2015 laboratory totals: Taos County reported the largest share at or above 4 pCi/L, 71.9%, and Santa Fe County the smallest, 32.5%, with San Miguel County at 44.4% between. Farther out, Los Alamos County (77 miles away) at 38.3%, Sandoval County (110 miles away) at 24.7% and Bernalillo County (118 miles away) at 25.2% 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 Mora County in Zone 1, the map's highest label: a predicted county average above 4 pCi/L. USGS geology rates 74% of the county's land moderate radon potential.
Pooled shares: Radon411's sum of CDC's county counts for one period.
Mora County, Geology
The ground under Mora County
PredictedUSGS's geologic map splits Mora County: 73.6% of its land is moderate radon potential and 26.4% high. The map puts 47.3% of Mora County in the area it calls Great Plains Pecos Valley Section and 26.3% in Southern Great Plains, with one smaller area beside them. USGS gives the first a radon index of 9 and the second 10, both in the moderate band (9 to 11).
| Area | The rock, in USGS's words | Potential | Radon index | Share of land |
|---|---|---|---|---|
| Great Plains Pecos Valley Section | Triassic sandstone, siltstone, mudstone, Quaternary alluvial and eolian sand and silt. | Moderate | 9 | 47.3% |
| Southern Great Plains | Cretaceous sedimentary rocks including sandstone and shale. | Moderate | 10 | 26.3% |
| Rocky Mountains (southern extension) | Sandstone, siltstone, shale, volcanic sediments, and valley-fill alluvium. | High | 12 | 26.3% |
