Radon tests reported for Screven County, 2008 to 2017, laboratory
CDC holds 3 reported tests for Screven County over the 2008 to 2017 laboratory totals, with a median of 1.0 pCi/L: too few to describe a county (Radon411 reads a share from 30 tests up). Screven County beside the counties around it is how this page reads it.
What these figures count
Only 3 tests were reported to CDC for Screven 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).
Screven County, Compared
Screven County radon figures, compared
Calculated by Radon411CDC's largest figure for Screven County rests on 5 tests over the 2007 to 2016 laboratory totals, 0 of them at or above 4 pCi/L, so each test moves its share by 20.0 points and no rank or comparison is drawn from it. Results reached as high as 1.1 pCi/L, with a middle value of 0.7 pCi/L.
The nearest counties with a figure are Richmond County (50 miles away) at 0.0%, Chatham County (59 miles away) at 0.0% and Columbia County (66 miles away) at 9.7%. 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 Screven 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.

Screven County, Geology
The ground under Screven County
PredictedUSGS's geologic map puts all of Screven County's mapped land in one class: low radon potential. The map puts 89.5% of Screven County in the area it calls Coastal Plain and 10.3% in Coastal Plain. 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 | 89.5% |
| Coastal Plain | Quaternary and Pleistocene-Pliocene coastal sand and gravel, lagoon and marsh clay and silt. | Low | 7 | 10.3% |

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