Lumpkin County radon figures, compared

Calculated by Radon411

In Lumpkin County, about 5 in 10 reported tests over the 2008 to 2017 laboratory totals (63 of 136) were at or above EPA's action level. Against the national pool of 35.7%, the gap is 10.6 points higher. Across 129 Georgia counties pooled together, 24.8% of tests reached that level, so Lumpkin County runs 21.5 points above its state.

Of 5 neighbours with a figure, none reported a larger share at or above 4 pCi/L; the spread is 21.8% (Dawson County) to 44.7% (Fannin County). By share, Lumpkin County is 4th of 57 Georgia counties with 30 or more tests for the same period.

Half the tests came in under 3.6 pCi/L and half over it; the single highest reached 23.1 pCi/L. Below the action level, 35 tests (25.7%) came in under 2 pCi/L, against 44.0% statewide, and 38 tests (27.9%) fell between 2 and 4, against 31.2% statewide.

Zone 2 on EPA's map (predicted average between 2 and 4 pCi/L) and a 46.3% share point the same way here. USGS geology rates 100% of the county's land moderate radon potential. CDC also counts 15 tests taken after mitigation in Lumpkin County for the same period: tests in homes where a fix was already in.

CDC's ten-year totals for Lumpkin County went from 161 tests (2005 to 2014) to 136 (2008 to 2017), the share going from 36.6% to 46.3%.

Lumpkin County, Geology

The ground under Lumpkin County

Predicted

USGS's geologic map puts all of Lumpkin County's mapped land in one class: moderate radon potential. The map puts 80.1% of Lumpkin County in the area it calls Georgiabama Thrust Stack (North) and 19.9% in Georgiabama Thrust Stack (South). USGS gives both a radon index of 9, in the moderate band (9 to 11).
