The ground under Benton County
PredictedUSGS's geologic map puts all of Benton County's mapped land in one class: low radon potential. All of it lies in the area the map calls North Central Hills/Flatwoods, to which USGS gives a radon index of 8, in the low band (5 to 8).
| Area | The rock, in USGS's words | Potential | Radon index | Share of land |
|---|---|---|---|---|
| North Central Hills/Flatwoods | Tertiary nonmarine to deltaic sediments ranging from sand to clay. | Low | 8 | 100% |
