Measured: tests reported to CDC
CDC holds 15 reported tests for Chattooga County over the 2008 to 2017 laboratory totals, with a median of 5.0 pCi/L: too few to describe a county (Radon411 reads a share from 30 tests up). Chattooga County beside the counties around it is how this page reads it.
Only 15 tests were reported to CDC for Chattooga 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).
Chattooga County, Compared
CDC's largest figure for Chattooga County rests on 15 tests over the 2008 to 2017 laboratory totals, 9 of them at or above 4 pCi/L, so each test moves its share by 6.7 points and no rank or comparison is drawn from it. Results reached as high as 16.1 pCi/L, with a middle value of 5.0 pCi/L.
Of the counties bordering it, 3 have a figure over the 2007 to 2016 laboratory totals: Walker County reported the largest share at or above 4 pCi/L, 19.2%, and DeKalb County, AL the smallest, 9.5%, with Floyd County at 17.1% between. Farther out, Gordon County (27 miles away) at 34.4%, Whitfield County (31 miles away) at 16.8% and Catoosa County (32 miles away) at 17.9% have figures too.

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 Chattooga 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.

Chattooga County, Geology
USGS's geologic map puts all of Chattooga County's mapped land in one class: low radon potential. All of it lies in the area the map calls Rome-Kingston Thrust Stack, 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 |
|---|---|---|---|---|
| Rome-Kingston Thrust Stack | Limestone and shale. | Low | 8 | 100% |

Across Georgia 26.5% of the land is rated moderate; none of Chattooga County's is. Of the 4 counties that border it, 2 have more high-potential ground, Cherokee County, AL the most at 8.2%.
