Kiowa County, Compared
Kiowa County radon figures, compared
Calculated by Radon411CDC's county radon counts over the 2006 to 2015 laboratory totals cover 53 Oklahoma counties, and Kiowa 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 (99 miles away) at 8.9%, Tulsa County (190 miles away) at 6.0% and Washington County (213 miles away) at 11.3%. 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 Kiowa 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.

The ground under Kiowa County
PredictedUSGS's geologic map puts all of Kiowa County's mapped land in one class: low radon potential. The map puts 59.9% of Kiowa County in the area it calls Wichita Mountains and 40.1% in Central Oklahoma Plains and Hills. USGS gives the first a radon index of 6 and the second 7, both in the low band (5 to 8).
| Area | The rock, in USGS's words | Potential | Radon index | Share of land |
|---|---|---|---|---|
| Wichita Mountains | Granite, rhyolite, abd gabbro. | Low | 6 | 59.9% |
| 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 | 40.1% |
