Sabine County, Compared
Sabine County radon figures, compared
Calculated by Radon411Sabine 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%.
The nearest counties with a figure are Smith County (110 miles away) at 9.1%, Montgomery County (122 miles away) at 7.1% and Harris County (138 miles away) at 3.1%. 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 Sabine 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.

Sabine County, Geology
The ground under Sabine County
PredictedUSGS's geologic map puts all of Sabine County's mapped land in one class: low radon potential. 97.7% of it lies in the area the map calls East Texas Province, to which USGS gives a radon index of 6, in the low band (5 to 8).
| Area | The rock, in USGS's words | Potential | Radon index | Share of land |
|---|---|---|---|---|
| East Texas Province | Cretaceous through Quaternary marine sandstone, shale, chalk, limestone, siltstone, clay, and lignite. | Low | 6 | 97.7% |
| Coastal Plain | Cretaceous through Quaternary marine sandstone, shale, chalk, limestone, siltstone, clay, and lignite. | Low | 7 | 2.0% |

Sabine County beside the ground around it
Across Texas 0.5% of the land is rated high; none of Sabine County's is. None of the 5 counties that border it has any moderate-potential ground either.
