Locations and reports
EPA puts Brooks County in Zone 3, its lowest radon zone, and only 3 radon tests from it are on file with CDC (2008 to 2017, laboratory totals). Homes with elevated levels occur in all three zones, so only a test measures yours.

Measured: tests reported to CDC
CDC holds 3 reported tests for Brooks County over the 2008 to 2017 laboratory totals, with a median of 1.7 pCi/L: too few to describe a county (Radon411 reads a share from 30 tests up). Brooks County beside the counties around it is how this page reads it.
Only 3 tests were reported to CDC for Brooks County over 2008 to 2017 (laboratory totals), and tests are often run on homes being sold or already suspected of a problem: so few describe neither the county nor this house.
Measured: CDC tracking data. Figure above: 2008 to 2017, laboratory. Measured data period: 2005 to 2017 (every CDC figure on file).
Brooks County, Compared
CDC's largest figure for Brooks County rests on 3 tests over the 2008 to 2017 laboratory totals, 0 of them at or above 4 pCi/L, so each test moves its share by 33.3 points and no rank or comparison is drawn from it. Results reached as high as 1.9 pCi/L, with a middle value of 1.7 pCi/L.
Jefferson County, FL, the one bordering county with a figure over the 2007 to 2016 laboratory totals, reported 4.7% of its tests at or above 4 pCi/L. Farther out, Dougherty County (61 miles away) at 0.0%, Houston County (112 miles away) at 8.2% and Laurens County (118 miles away) at 16.1% have figures too. Pooled across 137 Georgia counties, 23.9% of reported tests reached that level; across every county in the country with a figure, 35.8%.
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 Brooks 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.
Pooled shares: Radon411's sum of CDC's county counts for one period.
Brooks County, Geology
USGS's geologic map puts all of Brooks County's mapped land in one class: low radon potential. All of it lies in the area the map calls Coastal Plain, 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 |
|---|---|---|---|---|
| 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 | 100% |
Names, descriptions and indexes: U.S. Geological Survey, Geologic Radon Potential Map (2025). Shares: Radon411, from the map cut to the boundary.
Across Georgia 26.5% of the land is rated moderate; none of Brooks 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.

No CDC figure names Brooks County; the nearest county with one, Dougherty County (61 miles away), reported 0.0% of its tests at or above 4 pCi/L over the 2007 to 2016 laboratory totals, the only reading nearby until a test of this home. Zone 3 is the lowest label, yet homes at or above 4 pCi/L occur in every zone: a short-term kit (2 to 90 days) is the quick first check in Brooks County.
