Whitfield County, Compared

Whitfield County radon figures, compared

Calculated by Radon411

Whitfield County's 102 reported tests over the 2008 to 2017 laboratory totals had a middle value of 1.2 pCi/L and a maximum of 12.2 pCi/L, and 20.6% reached 4 pCi/L. Georgia as a whole (129 Georgia counties, pooled) comes to 24.8%: 4.2 points higher than here.

Among its state's counties it ranks 37th 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, 69 tests (67.6%) came in under 2 pCi/L, against 44.0% statewide, and 12 tests (11.8%) fell between 2 and 4, against 31.2% statewide. CDC's ten-year totals for Whitfield County went from 89 tests (2005 to 2014) to 102 (2008 to 2017), the share going from 20.2% to 20.6%.

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

Next door, the shares run from 18.6% in Catoosa County to 31.4% in Gordon County, with Hamilton County, TN and Catoosa County below Whitfield County.

CDC also counts 5 tests taken after mitigation in Whitfield County for the same period: tests in homes where a fix was already in.

The ground under Whitfield County

Predicted

USGS's geologic map puts all of Whitfield County's mapped land in one class: low radon potential. All of it lies in the area the map calls Rome-Kingston Thrust Stack, to which USGS gives a radon index of 8, in the low band (5 to 8).
