Franklin County, Geology
USGS's geologic map puts all of Franklin County's mapped land in one class: low radon potential. 99.5% of it lies in the area the map calls Pine Hills, 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 |
|---|---|---|---|---|
| Pine Hills | Sand, sandstone, bentonitic clay, quartzite, gravel, tuff, and siltstone. | Low | 6 | 99.5% |
| Loess Hills | Loess. | Low | 7 | 0.5% |

Across Mississippi 0.1% of the land is rated high; none of Franklin County's is. None of the 5 counties that border it has any moderate-potential ground either.
