Radon tests reported for Lincoln County, 2008 to 2017, laboratory
CDC holds 1 reported test for Lincoln County over the 2008 to 2017 laboratory totals, a result of 0.1 pCi/L: too few to describe a county (Radon411 reads a share from 30 tests up). Lincoln County beside the counties around it is how this page reads it.
What these figures count
Only 1 test was reported to CDC for Lincoln County over 2008 to 2017 (laboratory totals), and tests are often run on homes being sold or already suspected of a problem: so few describe neither the county nor this house.
Measured: CDC tracking data. Figure above: 2008 to 2017, laboratory. Measured data period: 2005 to 2017 (every CDC figure on file).
Lincoln County, Compared
Lincoln County radon figures, compared
Calculated by Radon411CDC's largest figure for Lincoln County rests on 6 tests over the 2005 to 2014 laboratory totals, 0 of them at or above 4 pCi/L, so each test moves its share by 16.7 points and no rank or comparison is drawn from it. Results reached as high as 2.1 pCi/L, with a middle value of 0.1 pCi/L.
Of the counties bordering it, 2 have a figure over the 2007 to 2016 laboratory totals: Elbert County reported the largest share at or above 4 pCi/L, 16.9%, and Columbia County the smallest, 9.7%. Farther out, Oglethorpe County (37 miles away) at 29.2%, Richmond County (37 miles away) at 0.0% and Greene County (44 miles away) at 16.7% have figures too. Pooled across 137 Georgia counties, 23.9% of reported tests reached that level; across every county in the country with a figure, 35.8%.
Statewide for the same period, Barrow County reported the highest share (51.0%) and Dougherty County the lowest (0.0%). EPA's 1993 map puts Lincoln County in Zone 3, its lowest label: a predicted county average under 2 pCi/L. USGS geology rates 100% of the county's land low radon potential.

Lincoln County, Geology
The ground under Lincoln County
PredictedUSGS's geologic map puts all of Lincoln County's mapped land in one class: low radon potential. The map puts 65.5% of Lincoln County in the area it calls Little River Thrust Stack and 34.3% in Carolina Slate Belt. USGS gives the first a radon index of 7 and the second 8, both in the low band (5 to 8).
| Area | The rock, in USGS's words | Potential | Radon index | Share of land |
|---|---|---|---|---|
| Little River Thrust Stack | Biotite and amphibolite gneiss, granite gneiss, mica schist. | Low | 7 | 65.5% |
| Carolina Slate Belt | Amphibolite, granitic gneiss, quartzite, muscovite schist, meta-argillite, metavolcanic rocks. | Low | 8 | 34.3% |

Lincoln County beside the ground around it
Across Georgia 26.5% of the land is rated moderate; none of Lincoln County's is. Of the 5 counties that border it, 2 have more moderate-potential ground, Elbert County the most at 73.4%.
