Calculated by Radon411

Jones County's 31 reported tests over the 2008 to 2017 laboratory totals had a middle value of 2.2 pCi/L and a maximum of 14.8 pCi/L, and 29.0% reached 4 pCi/L. Georgia as a whole (129 Georgia counties, pooled) comes to 24.8%: 4.2 points lower than here.

Among its state's counties it ranks 24th 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, 15 tests (48.4%) came in under 2 pCi/L, against 44.0% statewide, and 7 tests (22.6%) fell between 2 and 4, against 31.2% statewide. CDC's ten-year totals for Jones County went from 30 tests (2005 to 2014) to 31 (2008 to 2017), the share going from 16.7% to 29.0%.

EPA's 1993 zone map puts Jones County in Zone 3, a predicted county average under 2 pCi/L. USGS geology rates 100% of the county's land low radon potential.

Next door, the shares run from 1.0% in Bibb County to 30.0% in Putnam County, with Monroe County and Bibb County below Jones County.
