Radon tests reported for Le Flore County, 2008 to 2017, laboratory
CDC holds 9 reported tests for Le Flore County over the 2008 to 2017 laboratory totals, with a median of 0.8 pCi/L: too few to describe a county (Radon411 reads a share from 30 tests up). Le Flore County beside the counties around it is how this page reads it.
What these figures count
Only 9 tests were reported to CDC for Le Flore 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).
Le Flore County, Compared
Le Flore County radon figures, compared
Calculated by Radon411CDC's largest figure for Le Flore County rests on 9 tests over the 2008 to 2017 laboratory totals, 0 of them at or above 4 pCi/L, so each test moves its share by 11.1 points and no rank or comparison is drawn from it. Results reached as high as 2.4 pCi/L, with a middle value of 0.8 pCi/L.
The nearest counties with a figure are Cherokee County (71 miles away) at 32.0%, Delaware County (104 miles away) at 44.7% and Tulsa County (109 miles away) at 6.0%. 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 Le Flore 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 Le Flore County
PredictedUSGS's geologic map puts all of Le Flore County's mapped land in one class: low radon potential. The map puts 53.6% of Le Flore County in the area it calls Ouachita Mountains and 46.3% in Lower Arkansas River 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 |
|---|---|---|---|---|
| Ouachita Mountains | Mississippian and Pennsylvanian limestone, sandstone, siltstone, shale, conglomerate. | Low | 8 | 53.6% |
| Lower Arkansas River Valley | Pennsylvanian sandstone, siltstone, shale. | Low | 8 | 46.3% |
