Radon tests reported for Payne County, 2008 to 2017, laboratory
CDC holds 15 reported tests for Payne County over the 2008 to 2017 laboratory totals, with a median of 0.7 pCi/L: too few to describe a county (Radon411 reads a share from 30 tests up). Payne County beside the counties around it is how this page reads it.
What these figures count
Only 15 tests were reported to CDC for Payne 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).
Payne County, Compared
Payne County radon figures, compared
Calculated by Radon411CDC's largest figure for Payne County rests on 16 tests over the 2007 to 2016 laboratory totals, 1 of them at or above 4 pCi/L, so each test moves its share by 6.3 points and no rank or comparison is drawn from it. Results reached as high as 5.5 pCi/L, with a middle value of 0.8 pCi/L.
The nearest counties with a figure are Oklahoma County (44 miles away) at 8.9%, Tulsa County (58 miles away) at 6.0% and Washington County (74 miles away) at 11.3%. 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 Payne 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.

Payne County, Geology
The ground under Payne County
PredictedUSGS's geologic map puts all of Payne County's mapped land in one class: low radon potential. All of it lies in the area the map calls Central Oklahoma Plains and Hills, to which USGS gives a radon index of 7, in the low band (5 to 8).
| Area | The rock, in USGS's words | Potential | Radon index | Share of land |
|---|---|---|---|---|
| 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 | 100% |

Payne County beside the ground around it
Across Oklahoma 0.6% of the land is rated high; none of Payne County's is. None of the 5 counties that border it has any moderate-potential ground either.
