RA100 short-term liquid scintillation radon test kit
- Lab fee extra
Method: Liquid scintillation
In home: 48 to 96 hours
Locations and reports
EPA puts Toombs County in Zone 3, its lowest radon zone, and only 1 radon test from it is on file with CDC (2008 to 2017, laboratory totals). Homes with elevated levels occur in all three zones, so only a test measures yours.

Measured: tests reported to CDC
CDC holds 1 reported test for Toombs County over the 2008 to 2017 laboratory totals, a result of 0.8 pCi/L: too few to describe a county (Radon411 reads a share from 30 tests up). Toombs County beside the counties around it is how this page reads it.
Only 1 test was reported to CDC for Toombs 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).
Toombs County, Compared
CDC's largest figure for Toombs County rests on 2 tests over the 2007 to 2016 laboratory totals, 0 of them at or above 4 pCi/L, so each test moves its share by 50.0 points and no rank or comparison is drawn from it. Results reached as high as 0.8 pCi/L, with a middle value of 0.8 pCi/L.
The nearest counties with a figure are Laurens County (42 miles away) at 16.1%, Chatham County (71 miles away) at 0.0% and Houston County (82 miles away) at 8.2%. 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 Toombs 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.
Toombs County, Geology
USGS's geologic map puts all of Toombs 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 | 100% |

Across Georgia 26.5% of the land is rated moderate; none of Toombs County's is. None of the 7 counties that border it has any moderate-potential ground either.
The map rates the ground, not the air in any home.

No CDC figure names Toombs County; the nearest county with one, Laurens County (42 miles away), reported 16.1% of its tests at or above 4 pCi/L over the 2007 to 2016 laboratory totals, the only reading nearby until a test of this home. Zone 3 is the lowest label, yet homes at or above 4 pCi/L occur in every zone: a short-term kit (2 to 90 days) is the quick first check in Toombs County.

Toombs County, Cities and towns
The Census Bureau estimates 27,545 residents in Toombs County for July 1, 2025, 465 more than in 2020 (+1.7%). That works out to 76 people per square mile of land. Vidalia, the largest place on its list (10,885 residents in all), extends beyond Toombs County, so no share of the total is worked out for it. Reported testing is thin here: 2 tests over 2007 to 2016, or 0.1 for every 1,000 residents (2025 estimate), where Georgia as a whole comes to 2.6.
From Vidalia to Santa Claus, CDC publishes no figure by town: each reads Toombs County's.
| Place | Residents | Since 2020 | Share of residents |
|---|---|---|---|
| Vidaliaextends beyond Toombs County | 10,885 | +1.6% | Counted whole |
| Lyons | 4,260 | +0.3% | 15.5% |
| Santa Claus | 202 | +0.5% | 0.7% |
3 incorporated places, as listed in the U.S. Census Bureau’s 2020 place reference files. Residents: U.S. Census Bureau population estimates for July 1, 2025 (Vintage 2025). A place that extends beyond Toombs County is counted whole, so it has no share.
