Radon tests reported for Winston County, 2008 to 2017, laboratory
CDC holds 12 reported tests for Winston 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). Winston County beside the counties around it is how this page reads it.
What these figures count
Only 12 tests were reported to CDC for Winston 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).
Winston County, Compared
Winston County radon figures, compared
Calculated by Radon411CDC's largest figure for Winston County rests on 16 tests over the 2005 to 2014 laboratory totals, 0 of them at or above 4 pCi/L, so each test moves its share by 6.3 points and no rank or comparison is drawn from it. Results reached as high as 3.0 pCi/L, with a middle value of 1.4 pCi/L.
Of the counties bordering it, 3 have a figure over the 2008 to 2017 laboratory totals: Franklin County reported the largest share at or above 4 pCi/L, 18.1%, and Cullman County the smallest, 11.4%, with Lawrence County at 16.2% between. Farther out, Morgan County (36 miles away) at 14.6%, Colbert County (45 miles away) at 36.2% and Blount County (48 miles away) at 13.6% have figures too. Pooled across 65 Alabama counties, 21.9% of reported tests reached that level; across every county in the country with a figure, 35.7%.
Statewide for the same period, Colbert County reported the highest share (36.2%) and Baldwin County the lowest (0.0%). EPA's 1993 map puts Winston County in Zone 2, its middle label: a predicted county average between 2 and 4 pCi/L. USGS geology rates 100% of the county's land moderate radon potential.

The ground under Winston County
PredictedUSGS's geologic map puts all of Winston County's mapped land in one class: moderate radon potential. The map puts 91.2% of Winston County in the area it calls Appalachian Plateau and 8.8% in Inner Coastal Plain. USGS gives the first a radon index of 9 and the second 10, both in the moderate band (9 to 11).
| Area | The rock, in USGS's words | Potential | Radon index | Share of land |
|---|---|---|---|---|
| Appalachian Plateau | Limestone, sandstone, carbonaceous shale, coal | Moderate | 9 | 91.2% |
| Inner Coastal Plain | Marly sandy clay, chalk, and glauconitic sands. | Moderate | 10 | 8.8% |

Winston County beside the ground around it
Across Alabama 14.3% of the land is rated high; none of Winston County's is. Of the 5 counties that border it, 2 have more high-potential ground, Lawrence County the most at 71.1%.

Winston County, Cities and towns
Cities and towns in Winston County
The Census Bureau estimates 23,829 residents in Winston County for July 1, 2025, 326 more than in 2020 (+1.4%). That works out to 39 people per square mile of land. Haleyville, the largest place on its list (4,303 residents in all), extends beyond Winston County, so no share of the total is worked out for it. Reported testing is thin here: 16 tests over 2005 to 2014, or 0.7 for every 1,000 residents (2025 estimate), where Alabama as a whole comes to 2.7.
From Haleyville to Natural Bridge, CDC publishes no figure by town: each reads Winston County's.

7 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 Winston County is counted whole, so it has no share.
