Bosque County radon figures, compared
Calculated by Radon411Bosque County has no radon test figure of its own from CDC, whose counts over the 2007 to 2016 laboratory totals name 140 other Texas counties and leave it out. Pooled across 140 Texas counties, 10.4% of reported tests reached that level; across every county in the country with a figure, 35.8%.
McLennan County, the one bordering county with a figure over the 2007 to 2016 laboratory totals, reported 17.1% of its tests at or above 4 pCi/L. Farther out, Bell County (60 miles away) at 14.3%, Tarrant County (63 miles away) at 10.6% and Dallas County (78 miles away) at 8.7% have figures too. 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 Bosque 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.

Bosque County, Geology
The ground under Bosque County
PredictedUSGS's geologic map puts all of Bosque County's mapped land in one class: low radon potential. All of it lies in the area the map calls Central Texas/Gulf Coast Plain, 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/Gulf Coast Plain | Cretaceous through Quaternary marine sandstone, shale, chalk, limestone, siltstone, clay, and lignite. | Low | 7 | 100% |
