The ground under Tippah County
PredictedUSGS's geologic map splits Tippah County: 59.6% of its land is low radon potential and 40.4% moderate. The map puts 59.6% of Tippah County in the area it calls North Central Hills/Flatwoods and 40.4% in Pontotoc Ridge/Black Prairies. USGS gives the first a radon index of 8, in the low band (5 to 8), and the second 9, in the moderate band (9 to 11).
| 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 | 59.6% |
| Pontotoc Ridge/Black Prairies | Glauconitic sand, clay, sandy limestone, micaceous chalk, and lime. | Moderate | 9 | 40.4% |
