Measured: tests reported to CDC
CDC holds 4 reported tests for Logan County over the 2008 to 2017 laboratory totals, with a median of 1.8 pCi/L: too few to describe a county (Radon411 reads a share from 30 tests up). Logan County beside the counties around it is how this page reads it.
Only 4 tests were reported to CDC for Logan 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).
Logan County, Compared
CDC's largest figure for Logan County rests on 5 tests over the 2007 to 2016 laboratory totals, 1 of them at or above 4 pCi/L, so each test moves its share by 20.0 points and no rank or comparison is drawn from it. Results reached as high as 6.7 pCi/L, with a middle value of 2.1 pCi/L.
The nearest counties with a figure are Garland County (55 miles away) at 45.8%, Washington County (60 miles away) at 14.3% and Saline County (71 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 Logan 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.

Logan County, Geology
USGS's geologic map puts all of Logan County's mapped land in one class: low radon potential. All of it lies in the area the map calls Arkansas Valley, to which USGS gives a radon index of 8, in the low band (5 to 8).
| Area | The rock, in USGS's words | Potential | Radon index | Share of land |
|---|---|---|---|---|
| Arkansas Valley | Mississippian and Pennsylvanian sandstones and shales. | Low | 8 | 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 Logan County's is. None of the 6 counties that border it has any moderate-potential ground either.
