Radon tests reported for Choctaw County, 2008 to 2017, laboratory
CDC holds 1 reported test for Choctaw County over the 2008 to 2017 laboratory totals, a result of 0.8 pCi/L: too few to describe a county (Radon411 reads a share from 30 tests up). Choctaw County beside the counties around it is how this page reads it.
What these figures count
Only 1 test was reported to CDC for Choctaw 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).
Choctaw County, Compared
Choctaw County radon figures, compared
Calculated by Radon411CDC's largest figure for Choctaw 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 0.8 pCi/L, with a middle value of 0.8 pCi/L.
The nearest counties with a figure are Mobile County (85 miles away) at 3.8%, Baldwin County (95 miles away) at 0.0% and Tuscaloosa County (98 miles away) at 8.5%. 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 Choctaw 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.

Choctaw County, Geology
The ground under Choctaw County
PredictedUSGS's geologic map puts all of Choctaw County's mapped land in one class: low radon potential. The map puts 70.2% of Choctaw County in the area it calls Coastal Plain and 29.7% in Jackson Prairies. USGS gives the first a radon index of 7 and the second 8, both in the low band (5 to 8).
| Area | The rock, in USGS's words | Potential | Radon index | Share of land |
|---|---|---|---|---|
| Coastal Plain | Marly sandy clay, chalk, and glauconitic sands. | Low | 7 | 70.2% |
| Jackson Prairies | Sand, marl, clay, and limestone. | Low | 8 | 29.7% |

Cities and towns in Choctaw County
Choctaw County has been losing residents: from 12,623 in 2020 to 11,904 on July 1, 2025, a fall of 5.7% by the Census Bureau's estimates. That works out to 13 people per square mile of land.
