Radon Levels in Clay County, Georgia

Radon tests reported for Clay County, 2007 to 2016, laboratory
CDC holds 1 reported test for Clay County over the 2007 to 2016 laboratory totals, a result of 0.1 pCi/L: too few to describe a county (Radon411 reads a share from 30 tests up). Clay County beside the counties around it is how this page reads it.
What these figures count
Only 1 test was reported to CDC for Clay County over 2007 to 2016 (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: 2007 to 2016, laboratory. Measured data period: 2005 to 2016 (every CDC figure on file).
Clay County, Compared
Clay County radon figures, compared
Calculated by Radon411CDC's largest figure for Clay County rests on 1 test over the 2007 to 2016 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 0.1 pCi/L, with a middle value of 0.1 pCi/L.
The nearest counties with a figure are Dougherty County (45 miles away) at 0.0%, Muscogee County (61 miles away) at 2.1% and Harris County (77 miles away) at 10.9%. 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 Clay 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.

The ground under Clay County
PredictedMost of the ground under Clay County is one class on USGS's geologic map: 100% of its land is low radon potential, with 0.1% moderate. All of it lies in the area the map calls Coastal Plain, to which USGS gives a radon index of 8, 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 | 100% |

Clay County beside the ground around it
Georgia as a whole has more moderate-potential ground than Clay County: 26.5% of its land, against 0.1% here. Of the 6 counties that border it, 2 have more moderate-potential ground, Barbour County, AL the most at 59.5%.
