Locations and reports
EPA puts Geneva County in Zone 3, its lowest radon zone, and only 5 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 5 reported tests for Geneva County over the 2008 to 2017 laboratory totals, with a median of 1.2 pCi/L: too few to describe a county (Radon411 reads a share from 30 tests up). Geneva County beside the counties around it is how this page reads it.
Only 5 tests were reported to CDC for Geneva 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).
Geneva County, Compared
CDC's largest figure for Geneva County rests on 5 tests over the 2008 to 2017 laboratory totals, 0 of them at or above 4 pCi/L, so each test moves its share by 20.0 points and no rank or comparison is drawn from it. Results reached as high as 2.5 pCi/L, with a middle value of 1.2 pCi/L.
Jackson County, FL, the one bordering county with a figure over the 2008 to 2017 laboratory totals, reported 6.0% of its tests at or above 4 pCi/L. Farther out, Montgomery County (81 miles away) at 9.7%, Elmore County (105 miles away) at 22.2% and Lee County (108 miles away) at 12.3% have figures too. Pooled across 65 Alabama counties, 21.9% of reported tests reached that level; across every county in the country with a figure, 35.7%.
Statewide for the same period, Colbert County reported the highest share (36.2%) and Baldwin County the lowest (0.0%). EPA's 1993 map puts Geneva 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.

Geneva County, Geology
USGS's geologic map puts all of Geneva 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 7, in the low band (5 to 8).
| Area | The rock, in USGS's words | Potential | Radon index | Share of land |
|---|---|---|---|---|
| Coastal Plain | Marly sandy clay, chalk, and glauconitic sands. | Low | 7 | 99.7% |
Names, descriptions and indexes: U.S. Geological Survey, Geologic Radon Potential Map (2025). Shares: Radon411, from the map cut to the boundary.
Across Alabama 14.3% of the land is rated high; none of Geneva County's is. None of the 7 counties that border it has any moderate-potential ground either.
The map rates the ground, not the air in any home.
