Calculated by Radon411

White County's 91 reported tests over the 2008 to 2017 laboratory totals had a middle value of 2.7 pCi/L and a maximum of 28.0 pCi/L, and 25.3% reached 4 pCi/L. Georgia as a whole (129 Georgia counties, pooled) comes to 24.8%: 0.5 points lower than here.

Among its state's counties it ranks 30th of 57 Georgia counties with 30 or more tests for the same period. Statewide for the same period, Barrow County reported the highest share (48.3%) and Richmond County the lowest (0.0%).

Below the action level, 37 tests (40.7%) came in under 2 pCi/L, against 44.0% statewide, and 31 tests (34.1%) fell between 2 and 4, against 31.2% statewide. CDC's ten-year totals for White County went from 95 tests (2005 to 2014) to 91 (2008 to 2017), the share going from 23.2% to 25.3%.

EPA's 1993 zone map puts White County in Zone 2, a predicted county average between 2 and 4 pCi/L. USGS geology rates 100% of the county's land moderate radon potential.

Next door, the shares run from 31.9% in Towns County to 46.3% in Lumpkin County.

White County, Geology

The ground under White County

Predicted

USGS's geologic map puts all of White County's mapped land in one class: moderate radon potential. The map puts 68.3% of White County in the area it calls Georgiabama Thrust Stack (South) and 31.7% in Georgiabama Thrust Stack (North). USGS gives both a radon index of 9, in the moderate band (9 to 11).
