Gordon County, Compared

Gordon County radon figures, compared

Calculated by Radon411

In Gordon County, about 3 in 10 reported tests over the 2008 to 2017 laboratory totals (11 of 35) were at or above EPA's action level. Against the national pool of 35.7%, the gap is 4.3 points lower. Across 129 Georgia counties pooled together, 24.8% of tests reached that level, so Gordon County runs 6.6 points above its state.

Of 7 neighbours with a figure, 2 reported a larger share at or above 4 pCi/L and 5 a smaller one; the spread is 17.6% (Cherokee County) to 46.6% (Gilmer County). By share, Gordon County is 20th of 57 Georgia counties with 30 or more tests for the same period.

Half the tests came in under 2.1 pCi/L and half over it; the single highest reached 8.1 pCi/L. Below the action level, 17 tests (48.6%) came in under 2 pCi/L, against 44.0% statewide, and 7 tests (20.0%) fell between 2 and 4, against 31.2% statewide.

The reported tests do not follow EPA's Zone 3 label for Gordon County (predicted average under 2 pCi/L): 31.4% of them reached 4 pCi/L, more than a low-potential zone suggests. USGS geology rates 90% of the county's land low radon potential.

CDC's ten-year totals for Gordon County went from 18 tests (2005 to 2014) to 35 (2008 to 2017), the share going from 55.6% to 31.4%.

Gordon County, Geology

The ground under Gordon County

Predicted

Most of the ground under Gordon County is one class on USGS's geologic map: 90.4% of its land is low radon potential, with 9.6% moderate. The map puts 90.4% of Gordon County in the area it calls Rome-Kingston Thrust Stack and 9.6% in Georgiabama Thrust Stack (North). USGS gives the first a radon index of 8, in the low band (5 to 8), and the second 9, in the moderate band (9 to 11).
