Radon tests reported for Telfair County, 2008 to 2017, laboratory
CDC holds 2 reported tests for Telfair 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). Telfair County beside the counties around it is how this page reads it.
What these figures count
Only 2 tests were reported to CDC for Telfair 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: 2007 to 2017 (every CDC figure on file).
Telfair County, Compared
Telfair County radon figures, compared
Calculated by Radon411CDC's largest figure for Telfair County rests on 2 tests over the 2008 to 2017 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 2.3 pCi/L, with a middle value of 1.6 pCi/L.
The nearest counties with a figure are Laurens County (37 miles away) at 16.1%, Houston County (56 miles away) at 8.2% and Bibb County (75 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 Telfair 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.

Telfair County, Geology
The ground under Telfair County
PredictedUSGS's geologic map puts all of Telfair 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% |

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

Telfair County, Cities and towns
Cities and towns in Telfair County
Telfair County has been losing residents: from 12,449 in 2020 to 11,195 on July 1, 2025, a fall of 10.1% by the Census Bureau's estimates. That works out to 26 people per square mile of land. McRae-Helena, the largest place on its list (5,443 residents in all), extends beyond Telfair County, so no share of the total is worked out for it. Reported testing is thin here: 2 tests over 2008 to 2017, or 0.2 for every 1,000 residents (2025 estimate), where Georgia as a whole comes to 2.7.
From McRae-Helena to Jacksonville, CDC publishes no figure by town: each reads Telfair County's.
