Crane County, Compared
CDC's county radon counts over the 2007 to 2016 laboratory totals cover 140 Texas counties, and Crane County is not among them: no year's figure and no ten-year laboratory total names it. Pooled across 140 Texas counties, 10.4% of reported tests reached that level; across every county in the country with a figure, 35.8%.
The nearest counties with a figure are Midland County (42 miles away) at 1.0%, Lubbock County (156 miles away) at 57.8% and El Paso County (221 miles away) at 0.0%. 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 Crane County in Zone 3, its lowest label: a predicted county average under 2 pCi/L. USGS geology rates 99% of the county's land low radon potential.

Crane County, Geology
Most of the ground under Crane County is one class on USGS's geologic map: 99.1% of its land is low radon potential, with 0.9% moderate. 99.1% of it lies in the area the map calls Southern High Plains and Plateaus, 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 |
|---|---|---|---|---|
| Southern High Plains and Plateaus | Paleozoic and Mesozoic sandstone, limestone, shale. | Low | 7 | 99.1% |
| Western Mountains and Basins | Precambrian igneous rocks, silicic volcanic rocks, and alluvium. | Moderate | 9 | 0.9% |
