Radon tests reported for Decatur County, 2008 to 2017, laboratory
CDC holds 4 reported tests for Decatur County over the 2008 to 2017 laboratory totals, with a median of 1.6 pCi/L: too few to describe a county (Radon411 reads a share from 30 tests up). Decatur County beside the counties around it is how this page reads it.
What these figures count
Only 4 tests were reported to CDC for Decatur 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).
Decatur County, Compared
Decatur County radon figures, compared
Calculated by Radon411CDC's largest figure for Decatur County rests on 5 tests over the 2005 to 2014 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 2.9 pCi/L, with a middle value of 1.6 pCi/L.
Of the counties bordering it, 2 have a figure over the 2007 to 2016 laboratory totals: Jackson County, FL reported the largest share at or above 4 pCi/L, 6.1%, and Gadsden County, FL the smallest, 5.4%. Farther out, Dougherty County (50 miles away) at 0.0%, Muscogee County (114 miles away) at 2.1% and Houston County (121 miles away) at 8.2% 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 Decatur 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.
Pooled shares: Radon411's sum of CDC's county counts for one period.
Decatur County, Geology
The ground under Decatur County
PredictedUSGS's geologic map puts all of Decatur County's mapped land in one class: low radon potential. 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 | 99.8% |

Decatur County beside the ground around it
Across Georgia 26.5% of the land is rated moderate; none of Decatur County's is. None of the 7 counties that border it has any moderate-potential ground either.
