Locations and reports
EPA puts Dade County in Zone 3, its lowest radon zone, and only 17 radon tests from it are 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 17 reported tests for Dade County over the 2008 to 2017 laboratory totals, with a median of 1.5 pCi/L: too few to describe a county (Radon411 reads a share from 30 tests up). Dade County beside the counties around it is how this page reads it.
Only 17 tests were reported to CDC for Dade 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).
Dade County, Compared
CDC's largest figure for Dade County rests on 22 tests over the 2007 to 2016 laboratory totals, 6 of them at or above 4 pCi/L, so each test moves its share by 4.5 points and no rank or comparison is drawn from it. Results reached as high as 11.4 pCi/L, with a middle value of 1.4 pCi/L.
Of the counties bordering it, 5 have a figure over the 2007 to 2016 laboratory totals: Marion County, TN reported the largest share at or above 4 pCi/L, 29.6%, and DeKalb County, AL the smallest, 9.5%, with Walker County at 19.2%, Hamilton County, TN at 18.8% and Jackson County, AL at 17.4% between. Farther out, Catoosa County (21 miles away) at 17.9%, Whitfield County (31 miles away) at 16.8% and Gordon County (43 miles away) at 34.4% 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 Dade County in Zone 3, its lowest label: a predicted county average under 2 pCi/L. USGS geology rates 90% of the county's land low radon potential.

Dade County, Geology
Most of the ground under Dade County is one class on USGS's geologic map: 89.6% of its land is low radon potential, with 10.3% high and 0.1% moderate. The map puts 64.0% of Dade County in the area it calls Rome-Kingston Thrust Stack and 25.6% in Appalachian Plateau, with one smaller area beside them. USGS gives both 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 |
|---|---|---|---|---|
| Rome-Kingston Thrust Stack | Limestone and shale. | Low | 8 | 64.0% |
| Appalachian Plateau | Limestone, sandstone, carbonaceous shale, coal | Low | 8 | 25.6% |
| Interior Low Plateaus | Mississippian carbonate rocks and shales. | High | 12 | 10.3% |

Dade County, Cities and towns
Dade County's population has barely moved since 2020: 16,154 residents on July 1, 2025 against 16,233 then, by the Census Bureau's estimates. That works out to 93 people per square mile of land. Trenton, its one incorporated place, has 2,236 residents, 13.8% of the total. Reported testing is thin here: 22 tests over 2007 to 2016, or 1.4 for every 1,000 residents (2025 estimate), where Georgia as a whole comes to 2.6.
Trenton is the one incorporated place here; CDC publishes no figure by town, so it reads Dade County's.
