Predicted: EPA radon zone

EPA Zone 3: lower predicted potential

is EPA's lowest class, and its forecast for Toombs County as a whole is an average indoor of less than 2 pCi/L (less than 75 Bq/m³). A low zone clears no address in it: homes above EPA's turn up in all three zones.

Measured: tests reported to CDC

Radon tests reported for Toombs County, 2008 to 2017, laboratory

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.

What these figures count

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

Toombs County radon figures, compared

Calculated by Radon411

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.

Toombs County, Geology

The ground under Toombs County

Predicted

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).

Toombs County, Cities and towns

Cities and towns in Toombs County

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.
