The ground under Wood County
PredictedUSGS's geologic map puts all of Wood 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% |

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