Perry County, Geology
The ground under Perry County
PredictedUSGS's geologic map puts all of Perry County's mapped land in one class: low radon potential. All 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 | 100% |

Perry County beside the ground around it
Across Mississippi 0.1% of the land is rated high; none of Perry County's is. None of the 6 counties that border it has any moderate-potential ground either.
The map rates the ground, not the air in any home.
