CDC has published no radon test figures for Scott County. Garland County, 56 miles away, is the nearest county with a figure over the 2007 to 2016 laboratory totals.
Scott County, Compared
CDC's county radon counts over the 2007 to 2016 laboratory totals cover 60 Arkansas counties, and Scott County is not among them: no year's figure and no ten-year laboratory total names it. Pooled across 60 Arkansas counties, 22.7% of reported tests reached that level; across every county in the country with a figure, 35.8%.
The nearest counties with a figure are Garland County (56 miles away) at 45.8%, Washington County (78 miles away) at 14.3% and Saline County (80 miles away) at 31.9%. 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 Scott 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.
Scott County, Geology
USGS's geologic map puts all of Scott County's mapped land in one class: low radon potential. The map puts 85.7% of Scott County in the area it calls Athens Plateau/Fourche Mountains and 14.2% in Arkansas Valley. USGS gives both 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 |
|---|---|---|---|---|
| Athens Plateau/Fourche Mountains | Mississippian and Pennsylvanian sandstones and shales. | Low | 8 | 85.7% |
| Arkansas Valley | Mississippian and Pennsylvanian sandstones and shales. | Low | 8 | 14.2% |

Across Arkansas 21.3% of the land is rated moderate; none of Scott County's is. Of the 6 counties that border it, 2 have more moderate-potential ground, Montgomery County the most at 72.4%.
The map rates the ground, not the air in any home.
