Radon tests reported for Glascock County, 2005 to 2014, laboratory
CDC holds 1 reported test for Glascock County over the 2005 to 2014 laboratory totals, a result of 2.3 pCi/L: too few to describe a county (Radon411 reads a share from 30 tests up). Glascock County beside the counties around it is how this page reads it.
What these figures count
Only 1 test was reported to CDC for Glascock County over 2005 to 2014 (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. Measured data period: 2005 to 2014.
Glascock County, Compared
Glascock County radon figures, compared
Calculated by Radon411CDC's largest figure for Glascock County rests on 1 test over the 2005 to 2014 laboratory totals, 0 of them at or above 4 pCi/L, so each test moves its share by 100.0 points and no rank or comparison is drawn from it. Results reached as high as 2.3 pCi/L, with a middle value of 2.3 pCi/L.
The nearest counties with a figure are Columbia County (30 miles away) at 9.7%, Richmond County (32 miles away) at 0.0% and Greene County (40 miles away) at 16.7%. 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 Glascock 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.

Glascock County, Geology
The ground under Glascock County
PredictedUSGS's geologic map puts all of Glascock County's mapped land in one class: low radon potential. The map puts 93.6% of Glascock County in the area it calls Coastal Plain and 6.4% in Little River Thrust Stack. USGS gives the first a radon index of 8 and the second 7, both in the low band (5 to 8).
| Area | The rock, in USGS's words | Potential | Radon index | Share of land |
|---|---|---|---|---|
| Coastal Plain | Cretaceous and Tertiary marine and coastal sediments including limestone, sandstone, sand, silt, and clay. Coastal plan sands containing glauconite may generate locally elevated radon. | Low | 8 | 93.6% |
| Little River Thrust Stack | Biotite and amphibolite gneiss, granite gneiss, mica schist. | Low | 7 | 6.4% |

Glascock County beside the ground around it
Across Georgia 26.5% of the land is rated moderate; none of Glascock County's is. None of the 4 counties that border it has any moderate-potential ground either.
