Radon tests reported for Fayette County, 2008 to 2017, laboratory
CDC holds 2 reported tests for Fayette County over the 2008 to 2017 laboratory totals, with a median of 1.1 pCi/L: too few to describe a county (Radon411 reads a share from 30 tests up). Fayette County beside the counties around it is how this page reads it.
What these figures count
Only 2 tests were reported to CDC for Fayette 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).
Fayette County, Compared
Fayette County radon figures, compared
Calculated by Radon411CDC's largest figure for Fayette County rests on 3 tests over the 2007 to 2016 laboratory totals, 0 of them at or above 4 pCi/L, so each test moves its share by 33.3 points and no rank or comparison is drawn from it. Results reached as high as 1.5 pCi/L, with a middle value of 1.1 pCi/L.
Tuscaloosa County, the one bordering county with a figure over the 2008 to 2017 laboratory totals, reported 8.5% of its tests at or above 4 pCi/L. Farther out, Jefferson County (50 miles away) at 10.7%, Franklin County (50 miles away) at 18.1% and Cullman County (58 miles away) at 11.4% 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 Fayette 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.
Pooled shares: Radon411's sum of CDC's county counts for one period.
Fayette County, Geology
The ground under Fayette County
PredictedUSGS's geologic map puts all of Fayette County's mapped land in one class: moderate radon potential. The map puts 61.4% of Fayette County in the area it calls Appalachian Plateau and 38.6% 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 | 61.4% |
| Inner Coastal Plain | Marly sandy clay, chalk, and glauconitic sands. | Moderate | 10 | 38.6% |

Fayette County beside the ground around it
Across Alabama 14.3% of the land is rated high; none of Fayette County's is. Of the 5 counties that border it, none has as large a share of moderate-potential ground; Tuscaloosa County comes nearest at 100%.

Fayette County, Cities and towns
Cities and towns in Fayette County
About 15,872 people live in Fayette County by the Census Bureau's estimate for July 1, 2025, 459 fewer than in 2020 (−2.8%). That works out to 25 people per square mile of land. Winfield, the largest place on its list (4,842 residents in all), extends beyond Fayette County, so no share of the total is worked out for it. Reported testing is thin here: 3 tests over 2007 to 2016, or 0.2 for every 1,000 residents (2025 estimate), where Alabama as a whole comes to 2.5.
From Winfield to Gu-Win, CDC publishes no figure by town: each reads Fayette County's.
