Newton County, Compared
Newton County radon figures, compared
Calculated by Radon411Newton 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%.
Calcasieu Parish, LA, the one bordering county with a figure over the 2007 to 2016 laboratory totals, reported 0.0% of its tests at or above 4 pCi/L. Farther out, Montgomery County (110 miles away) at 7.1%, Harris County (117 miles away) at 3.1% and Galveston County (121 miles away) at 0.0% 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 Newton 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 Newton County
PredictedUSGS's geologic map puts all of Newton County's mapped land in one class: low radon potential. 98.1% of it lies in the area the map calls Coastal 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 |
|---|---|---|---|---|
| Coastal Plain | Cretaceous through Quaternary marine sandstone, shale, chalk, limestone, siltstone, clay, and lignite. | Low | 7 | 98.1% |
| East Texas Province | Cretaceous through Quaternary marine sandstone, shale, chalk, limestone, siltstone, clay, and lignite. | Low | 6 | 1.4% |
| Terraces and Prairies | Clay, sandy clay, silt, sand, and some gravel. | Low | 8 | 0.5% |

Newton County beside the ground around it
Across Texas 0.5% of the land is rated high; none of Newton County's is. None of the 7 counties that border it has any moderate-potential ground either.
