Radon tests reported for Wheeler County, 2008 to 2017, laboratory
CDC holds 2 reported tests for Wheeler County over the 2008 to 2017 laboratory totals, with a median of 1.4 pCi/L: too few to describe a county (Radon411 reads a share from 30 tests up). Wheeler County beside the counties around it is how this page reads it.
What these figures count
Only 2 tests were reported to CDC for Wheeler 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).
Wheeler County, Compared
Wheeler County radon figures, compared
Calculated by Radon411CDC's largest figure for Wheeler County rests on 3 tests over the 2007 to 2016 laboratory totals, 0 of them at or above 4 pCi/L, so each test moves its share by 33.3 points and no rank or comparison is drawn from it. Results reached as high as 3.4 pCi/L, with a middle value of 2.7 pCi/L.
The nearest counties with a figure are Potter County (92 miles away) at 20.0%, Randall County (97 miles away) at 71.4% and Lubbock County (152 miles away) at 57.8%. Pooled across 140 Texas counties, 10.4% of reported tests reached that level; across every county in the country with a figure, 35.8%.
Statewide for the same period, Randall County reported the highest share (71.4%) and Nueces County the lowest (0.0%). EPA's 1993 map puts Wheeler County in Zone 3, its lowest label: a predicted county average under 2 pCi/L. USGS geology rates 53% of the county's land low radon potential.

Wheeler County, Geology
The ground under Wheeler County
PredictedUSGS's geologic map splits Wheeler County: 52.6% of its land is low radon potential and 47.4% moderate. The map puts 52.5% of Wheeler County in the area it calls Central Texas and 47.4% in Northern High Plains and Plateaus. USGS gives the first a radon index of 7, in the low band (5 to 8), and the second 10, in the moderate band (9 to 11).
| Area | The rock, in USGS's words | Potential | Radon index | Share of land |
|---|---|---|---|---|
| Central Texas | Cretaceous through Quaternary marine sandstone, shale, chalk, limestone, siltstone, clay, and lignite. | Low | 7 | 52.5% |
| Northern High Plains and Plateaus | Tertiary sandstone, siltstone, shale. | Moderate | 10 | 47.4% |

Wheeler County beside the ground around it
Across Texas 0.5% of the land is rated high; none of Wheeler County's is. Of the 7 counties that border it, 4 have more moderate-potential ground, Hemphill County the most at 100%.
