EPA puts Putnam County in Zone 3, its lowest radon zone, and 30.0% of its 30 reported radon tests (2008 to 2017, laboratory totals) were at or above 4 pCi/L. Homes with elevated levels occur in all three zones, so only a test measures yours.

Putnam County, Compared
In Putnam County, about 3 in 10 reported tests over the 2008 to 2017 laboratory totals (9 of 30) were at or above EPA's action level. Against the national pool of 35.7%, the gap is 5.7 points lower. Across 129 Georgia counties pooled together, 24.8% of tests reached that level, so Putnam County runs 5.2 points above its state.
Of 3 neighbours with a figure, none reported a larger share at or above 4 pCi/L; the spread is 16.7% (Morgan County) to 29.0% (Jones County). By share, Putnam County is 22nd of 57 Georgia counties with 30 or more tests for the same period.
Half the tests came in under 2.2 pCi/L and half over it; the single highest reached 10.9 pCi/L. Below the action level, 12 tests (40.0%) came in under 2 pCi/L, against 44.0% statewide, and 9 tests (30.0%) fell between 2 and 4, against 31.2% statewide.
The reported tests do not follow EPA's Zone 3 label for Putnam County (predicted average under 2 pCi/L): 30.0% of them reached 4 pCi/L, more than a low-potential zone suggests. USGS geology rates 99% of the county's land low radon potential.
CDC's ten-year totals for Putnam County went from 32 tests (2005 to 2014) to 30 (2008 to 2017), the share going from 34.4% to 30.0%.

Putnam County, Geology
Most of the ground under Putnam County is one class on USGS's geologic map: 98.8% of its land is low radon potential, with 1.2% moderate. 98.8% of it lies in the area the map calls Little River Thrust Stack, to which USGS gives a radon index of 7, in the low band (5 to 8).
| Area | The rock, in USGS's words | Potential | Radon index | Share of land |
|---|---|---|---|---|
| Little River Thrust Stack | Biotite and amphibolite gneiss, granite gneiss, mica schist. | Low | 7 | 98.8% |
| Georgiabama Thrust Stack (South) | Schist, amphibolite and granite. | Moderate | 9 | 1.2% |
