Atoka County radon figures, compared
Calculated by Radon411CDC's county radon counts over the 2006 to 2015 laboratory totals cover 53 Oklahoma counties, and Atoka County is not among them: no year's figure and no ten-year laboratory total names it. Pooled across 53 Oklahoma counties, 12.6% of reported tests reached that level; across every county in the country with a figure, 36.3%.
The nearest counties with a figure are Oklahoma County (112 miles away) at 8.9%, Tulsa County (121 miles away) at 6.0% and Cherokee County (121 miles away) at 32.0%. Statewide for the same period, Delaware County reported the highest share (44.7%) and Tulsa County the lowest (6.0%).
EPA's 1993 map puts Atoka 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.

The ground under Atoka County
PredictedUSGS's geologic map puts all of Atoka County's mapped land in one class: low radon potential. The map puts 55.1% of Atoka County in the area it calls Ouachita Mountains and 37.7% in Gulf Coast Plain, with one smaller area beside them. 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 |
|---|---|---|---|---|
| Ouachita Mountains | Mississippian and Pennsylvanian limestone, sandstone, siltstone, shale, conglomerate. | Low | 8 | 55.1% |
| Gulf Coast Plain | Cretaceous shale, nonmarine sand and clay and marine limestone and clay. | Low | 8 | 37.7% |
| Central Oklahoma Plains and Hills | Nonmarine Permian and Tertiary rocks, including shale, sandstone, and conglomerate in the western part, and Mississippian and Pennsylvanian rocks in the eastern part. | Low | 7 | 7.2% |
