Radon tests reported for Childress County, 2008 to 2017, laboratory
CDC holds 1 reported test for Childress County over the 2008 to 2017 laboratory totals, a result of 1.1 pCi/L: too few to describe a county (Radon411 reads a share from 30 tests up). Childress County beside the counties around it is how this page reads it.
What these figures count
Only 1 test was reported to CDC for Childress 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: 2006 to 2017 (every CDC figure on file).
Childress County, Compared
Childress County radon figures, compared
Calculated by Radon411CDC's largest figure for Childress County rests on 1 test over the 2008 to 2017 laboratory totals, 0 of them at or above 4 pCi/L, so each test moves its share by 100.0 points and no rank or comparison is drawn from it. Results reached as high as 1.1 pCi/L, with a middle value of 1.1 pCi/L.
The nearest counties with a figure are Randall County (101 miles away) at 71.4%, Lubbock County (112 miles away) at 57.8% and Potter County (113 miles away) at 20.0%. 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 Childress County in Zone 3, its lowest label: a predicted county average under 2 pCi/L. USGS geology rates 100% of the county's land low radon potential.

The ground under Childress County
PredictedUSGS's geologic map puts all of Childress County's mapped land in one class: low radon potential. All of it lies in the area the map calls Central Texas, to which USGS gives a radon index of 7, in the low band (5 to 8).
| 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 | 99.9% |
