Rains County, Compared
Rains County radon figures, compared
Calculated by Radon411CDC's county radon counts over the 2007 to 2016 laboratory totals cover 140 Texas counties, and Rains 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 Smith County (46 miles away) at 9.1%, Collin County (50 miles away) at 7.7% and Dallas County (58 miles away) at 8.7%. 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 Rains 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.

Rains County, Geology
The ground under Rains County
PredictedUSGS's geologic map puts all of Rains County's mapped land in one class: low radon potential. All 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 | 100% |

Rains County beside the ground around it
Across Texas 0.5% of the land is rated high; none of Rains County's is. None of the 4 counties that border it has any moderate-potential ground either.
The map rates the ground, not the air in any home.
