Calculated by Radon411

Floyd County's 116 reported tests over the 2008 to 2017 laboratory totals had a middle value of 1.9 pCi/L and a maximum of 10.3 pCi/L, and 19.8% reached 4 pCi/L. Georgia as a whole (129 Georgia counties, pooled) comes to 24.8%: 5.0 points higher than here.

Among its state's counties it ranks 39th 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, 63 tests (54.3%) came in under 2 pCi/L, against 44.0% statewide, and 30 tests (25.9%) fell between 2 and 4, against 31.2% statewide. CDC's ten-year totals for Floyd County went from 102 tests (2005 to 2014) to 116 (2008 to 2017), the share going from 15.7% to 19.8%.

EPA's 1993 zone map puts Floyd 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 22.7% in Walker County to 31.4% in Gordon County.
