Radon tests reported for Irwin County, 2008 to 2017, laboratory
CDC holds 1 reported test for Irwin County over the 2008 to 2017 laboratory totals, a result of 0.1 pCi/L: too few to describe a county (Radon411 reads a share from 30 tests up). Irwin County beside the counties around it is how this page reads it.
What these figures count
Only 1 test was reported to CDC for Irwin 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: 2006 to 2017 (every CDC figure on file).
Irwin County, Compared
Irwin County radon figures, compared
Calculated by Radon411CDC's largest figure for Irwin County rests on 1 test over the 2008 to 2017 laboratory totals, 0 of them at or above 4 pCi/L, so each test moves its share by 100.0 points and no rank or comparison is drawn from it. Results reached as high as 0.1 pCi/L, with a middle value of 0.1 pCi/L.
The nearest counties with a figure are Dougherty County (56 miles away) at 0.0%, Laurens County (63 miles away) at 16.1% and Houston County (63 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 Irwin 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.
Irwin County, Geology
The ground under Irwin County
PredictedUSGS's geologic map puts all of Irwin 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% |

Irwin County beside the ground around it
Across Georgia 26.5% of the land is rated moderate; none of Irwin County's is. None of the 5 counties that border it has any moderate-potential ground either.
The map rates the ground, not the air in any home.

Irwin County, Cities and towns
Cities and towns in Irwin County
Irwin County has been losing residents: from 9,646 in 2020 to 9,020 on July 1, 2025, a fall of 6.5% by the Census Bureau's estimates. That works out to 25 people per square mile of land. Fitzgerald, the largest place on its list (8,882 residents in all), extends beyond Irwin County, so no share of the total is worked out for it. Reported testing is thin here: 1 test over 2008 to 2017, or 0.1 for every 1,000 residents (2025 estimate), where Georgia as a whole comes to 2.7.
From Fitzgerald to Ocilla, CDC publishes no figure by town: each reads Irwin County's.
| Place | Residents | Since 2020 | Share of residents |
|---|---|---|---|
| Fitzgeraldextends beyond Irwin County | 8,882 | −1.3% | Counted whole |
| Ocilla | 2,837 | −17.9% | 31.5% |
2 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 Irwin County is counted whole, so it has no share.
