Banks County, Compared
Banks County radon figures, compared
Calculated by Radon411In Banks County, about 4 in 10 reported tests over the 2008 to 2017 laboratory totals (20 of 57) were at or above EPA's action level. Against the national pool of 35.7%, the gap is 0.6 points lower. Across 129 Georgia counties pooled together, 24.8% of tests reached that level, so Banks County runs 10.3 points above its state.
Of 5 neighbours with a figure, 3 reported a larger share at or above 4 pCi/L and 2 a smaller one; the spread is 25.3% (Stephens County) to 40.0% (Jackson County). By share, Banks County is 14th of 57 Georgia counties with 30 or more tests for the same period.
Half the tests came in under 2.8 pCi/L and half over it; the single highest reached 21.8 pCi/L. Below the action level, 21 tests (36.8%) came in under 2 pCi/L, against 44.0% statewide, and 16 tests (28.1%) fell between 2 and 4, against 31.2% statewide.
Zone 2 on EPA's map (predicted average between 2 and 4 pCi/L) and a 35.1% share point the same way here. USGS geology rates 100% of the county's land moderate radon potential.
CDC's ten-year totals for Banks County went from 57 tests (2005 to 2014) to 57 (2008 to 2017), the share going from 29.8% to 35.1%.

The ground under Banks County
PredictedUSGS's geologic map puts all of Banks County's mapped land in one class: moderate radon potential. All of it lies in the area the map calls Georgiabama Thrust Stack (South), to which USGS gives a radon index of 9, in the moderate band (9 to 11).
| Area | The rock, in USGS's words | Potential | Radon index | Share of land |
|---|---|---|---|---|
| Georgiabama Thrust Stack (South) | Schist, amphibolite and granite. | Moderate | 9 | 100% |

Cities and towns in Banks County
Banks County is growing: the Census Bureau puts it at 21,273 residents on July 1, 2025, up 17.3% from 18,129 in 2020. That works out to 91 people per square mile of land. Baldwin, the largest place on its list (4,240 residents in all), extends beyond Banks County, so no share of the total is worked out for it.

From Baldwin to Gillsville, CDC publishes no figure by town: each reads Banks County's.
