Measured: tests reported to CDC
CDC holds 4 reported tests for Searcy County over the 2008 to 2017 laboratory totals, with a median of 3.5 pCi/L: too few to describe a county (Radon411 reads a share from 30 tests up). Searcy County beside the counties around it is how this page reads it.
Only 4 tests were reported to CDC for Searcy 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.

Searcy County, Compared
CDC's largest figure for Searcy County rests on 4 tests over the 2008 to 2017 laboratory totals, 2 of them at or above 4 pCi/L, so each test moves its share by 25.0 points and no rank or comparison is drawn from it. Results reached as high as 6.5 pCi/L, with a middle value of 3.5 pCi/L.
The nearest counties with a figure are Pulaski County (82 miles away) at 6.8%, Washington County (85 miles away) at 14.3% and Saline County (87 miles away) at 31.9%. 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 Searcy County in Zone 2, its middle label: a predicted county average between 2 and 4 pCi/L. USGS geology rates 73% of the county's land moderate radon potential.

Searcy County, Geology
USGS's geologic map splits Searcy County: 73.5% of its land is moderate radon potential and 26.5% low. The map puts 58.3% of Searcy County in the area it calls Springfield Plateau and 26.5% in Boston Mountains, with one smaller area beside them. USGS gives the first a radon index of 9, in the moderate band (9 to 11), and the second 8, in the low band (5 to 8).
| Area | The rock, in USGS's words | Potential | Radon index | Share of land |
|---|---|---|---|---|
| Springfield Plateau | Mississippian limestone, shale, and sandstone. | Moderate | 9 | 58.3% |
| Boston Mountains | Mississippian and Pennsylvanian sandstones and shales. | Low | 8 | 26.5% |
| Salem Plateau | Ordovician dolomite. | Moderate | 9 | 15.1% |
