The ground under Claiborne Parish
PredictedUSGS's geologic map puts all of Claiborne Parish's mapped land in one class: low radon potential. All of it lies in the area the map calls Old Uplands, 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 |
|---|---|---|---|---|
| Old Uplands | Clays, silts, sands, and ironstone. | Low | 7 | 100% |

Claiborne Parish beside the ground around it
Neither Claiborne Parish nor Louisiana as a whole has any land USGS rates above low potential. None of the 6 counties that border it has any moderate-potential ground either.
