Brantley County radon figures, compared
Calculated by Radon411CDC's county radon counts over the 2007 to 2016 laboratory totals cover 137 Georgia counties, and Brantley County is not among them: no year's figure and no ten-year laboratory total names it. Pooled across 137 Georgia counties, 23.9% of reported tests reached that level; across every county in the country with a figure, 35.8%.
The nearest counties with a figure are Chatham County (75 miles away) at 0.0%, Laurens County (103 miles away) at 16.1% and Houston County (132 miles away) at 8.2%. Statewide for the same period, Barrow County reported the highest share (51.0%) and Dougherty County the lowest (0.0%).
EPA's 1993 map puts Brantley County in Zone 3, its lowest label: a predicted county average under 2 pCi/L. USGS geology rates 100% of the county's land low radon potential.

Brantley County, Geology
The ground under Brantley County
PredictedUSGS's geologic map puts all of Brantley County's mapped land in one class: low radon potential. The map puts 92.5% of Brantley County in the area it calls Coastal Plain and 7.5% in Coastal Plain. USGS gives the first a radon index of 7 and the second 8, both in the low band (5 to 8).
| Area | The rock, in USGS's words | Potential | Radon index | Share of land |
|---|---|---|---|---|
| Coastal Plain | Quaternary and Pleistocene-Pliocene coastal sand and gravel, lagoon and marsh clay and silt. | Low | 7 | 92.5% |
| Coastal Plain | Cretaceous and Tertiary marine and coastal sediments including limestone, sandstone, sand, silt, and clay. Coastal plan sands containing glauconite may generate locally elevated radon. | Low | 8 | 7.5% |
