Radon tests reported for Choctaw County, 2008 to 2017, laboratory
CDC holds 2 reported tests for Choctaw County over the 2008 to 2017 laboratory totals, with a median of 4.8 pCi/L: too few to describe a county (Radon411 reads a share from 30 tests up). Choctaw County beside the counties around it is how this page reads it.
What these figures count
Only 2 tests were reported to CDC for Choctaw 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).
Choctaw County, Compared
Choctaw County radon figures, compared
Calculated by Radon411CDC's largest figure for Choctaw County rests on 2 tests over the 2008 to 2017 laboratory totals, 2 of them at or above 4 pCi/L, so each test moves its share by 50.0 points and no rank or comparison is drawn from it. Results reached as high as 4.9 pCi/L, with a middle value of 4.8 pCi/L.
The nearest counties with a figure are Cherokee County (133 miles away) at 32.0%, Tulsa County (146 miles away) at 6.0% and Oklahoma County (149 miles away) at 8.9%. Pooled across 53 Oklahoma counties, 12.6% of reported tests reached that level; across every county in the country with a figure, 36.3%.
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 Choctaw County in Zone 3, its lowest label: a predicted county average under 2 pCi/L. USGS geology rates 77% of the county's land low radon potential.

The ground under Choctaw County
PredictedMost of the ground under Choctaw County is one class on USGS's geologic map: 76.8% of its land is low radon potential, with 23.2% moderate.

USGS gives the first a radon index of 8, in the low band (5 to 8), and the second 10, in the moderate band (9 to 11).
| Area | The rock, in USGS's words | Potential | Radon index | Share of land |
|---|---|---|---|---|
| Gulf Coast Plain | Cretaceous shale, nonmarine sand and clay and marine limestone and clay. | Low | 8 | 76.6% |
| Cretaceous Gulfian series | Cretaceous sandstone, shale, limestone, siltstone. | Moderate | 10 | 23.2% |
