Radon tests reported for Warren County, 2008 to 2017, laboratory
CDC holds 2 reported tests for Warren County over the 2008 to 2017 laboratory totals, with a median of 0.5 pCi/L: too few to describe a county (Radon411 reads a share from 30 tests up). Warren County beside the counties around it is how this page reads it.
What these figures count
Only 2 tests were reported to CDC for Warren 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).
Warren County, Compared
Warren County radon figures, compared
Calculated by Radon411CDC's largest figure for Warren County rests on 3 tests over the 2006 to 2015 laboratory totals, 0 of them at or above 4 pCi/L, so each test moves its share by 33.3 points and no rank or comparison is drawn from it. Results reached as high as 2.5 pCi/L, with a middle value of 0.8 pCi/L.
The nearest counties with a figure are Columbia County (26 miles away) at 9.7%, Greene County (31 miles away) at 16.7% and Richmond County (35 miles away) at 0.0%. 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 Warren 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.

Warren County, Geology
The ground under Warren County
PredictedUSGS's geologic map puts all of Warren County's mapped land in one class: low radon potential. The map puts 81.5% of Warren County in the area it calls Little River Thrust Stack and 18.5% in Coastal Plain. 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 | 81.5% |
| 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 | 18.5% |

Warren County beside the ground around it
Across Georgia 26.5% of the land is rated moderate; none of Warren County's is. None of the 6 counties that border it has any moderate-potential ground either.
