Radon Levels in Jackson County, Georgia

EPA puts Jackson County in Zone 2, its middle radon zone, and high results are common there: 40.0% of the 460 radon tests reported to CDC (2008 to 2017, laboratory totals) came back at or above 4 pCi/L. Homes with elevated levels occur in all three zones, so only a test measures yours.

Predicted: EPA radon zone

EPA Zone 2: moderate predicted potential

Jackson County is a county: EPA's forecast for it as a whole is an average indoor of 2 to 4 pCi/L (75 to 150 Bq/m³). It describes no single address, and homes above EPA's are found in every zone, this one included.

Jackson County, Compared

Jackson County radon figures, compared

Calculated by Radon411

In Jackson County, about 4 in 10 reported tests over the 2008 to 2017 laboratory totals (184 of 460) were at or above EPA's action level. Against the national pool of 35.7%, the gap is 4.3 points higher. Across 129 Georgia counties pooled together, 24.8% of tests reached that level, so Jackson County runs 15.2 points above its state.

Of 7 neighbours with a figure, 1 reported a larger share at or above 4 pCi/L and 6 a smaller one; the spread is 12.8% (Clarke County) to 48.3% (Barrow County). By share, Jackson County is 10th of 57 Georgia counties with 30 or more tests for the same period.

Half the tests came in under 3.2 pCi/L and half over it; the single highest reached 30.1 pCi/L. Below the action level, 140 tests (30.4%) came in under 2 pCi/L, against 44.0% statewide, and 136 tests (29.6%) 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 40.0% share point the same way here. USGS geology rates 100% of the county's land moderate radon potential. CDC also counts 22 tests taken after mitigation in Jackson County for the same period: tests in homes where a fix was already in.

CDC's ten-year totals for Jackson County went from 315 tests (2005 to 2014) to 460 (2008 to 2017), the share going from 32.7% to 40.0%.

Jackson County, Geology

The ground under Jackson County

Predicted

USGS's geologic map puts all of Jackson 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).

Jackson County, Cities and towns

Cities and towns in Jackson County

Jackson County is growing: the Census Bureau puts it at 99,265 residents on July 1, 2025, up 29.3% from 76,765 in 2020. That works out to 292 people per square mile of land. Braselton, the largest place on its list (18,496 residents in all), extends beyond Jackson County, so no share of the total is worked out for it. Testing is reported here more often than across the state: CDC's 460 reported tests for 2008 to 2017 come to 4.6 for every 1,000 residents (2025 estimate), against 2.7 for Georgia.

From Braselton to Talmo, CDC publishes no figure by town: each reads Jackson County's.
