Measured: tests reported to CDC
CDC holds 1 reported test for Bradley 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). Bradley County beside the counties around it is how this page reads it.
Only 1 test was reported to CDC for Bradley 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).
Bradley County, Compared
CDC's largest figure for Bradley 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 Saline County (87 miles away) at 31.9%, Pulaski County (90 miles away) at 6.8% and Garland County (95 miles away) at 45.8%. Pooled across 60 Arkansas counties, 22.7% of reported tests reached that level; across every county in the country with a figure, 35.8%.
Statewide for the same period, Garland County reported the highest share (45.8%) and Pulaski County the lowest (6.8%). EPA's 1993 map puts Bradley 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.
Bradley County, Geology
USGS's geologic map puts all of Bradley County's mapped land in one class: low radon potential. All of it lies in the area the map calls West Gulf Coastal Plain, to which USGS gives a radon index of 7, in the low band (5 to 8).
| Area | The rock, in USGS's words | Potential | Radon index | Share of land |
|---|---|---|---|---|
| West Gulf Coastal Plain | Glauconitic, phosphatic, and carbonaceous sediments. | Low | 7 | 100% |
Names, descriptions and indexes: U.S. Geological Survey, Geologic Radon Potential Map (2025). Shares: Radon411, from the map cut to the boundary.
Across Arkansas 21.3% of the land is rated moderate; none of Bradley County's is. None of the 5 counties that border it has any moderate-potential ground either.
