Locations and reports

Measured: tests reported to CDC
CDC holds 3 reported tests for Pontotoc County over the 2008 to 2017 laboratory totals, with a median of 0.6 pCi/L: too few to describe a county (Radon411 reads a share from 30 tests up). Pontotoc County beside the counties around it is how this page reads it.
Only 3 tests were reported to CDC for Pontotoc 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.

Pontotoc County, Compared
CDC's largest figure for Pontotoc County rests on 3 tests over the 2008 to 2017 laboratory totals, 0 of them at or above 4 pCi/L, so each test moves its share by 33.3 points and no rank or comparison is drawn from it. Results reached as high as 0.8 pCi/L, with a middle value of 0.6 pCi/L.
The nearest counties with a figure are Oklahoma County (70 miles away) at 8.9%, Tulsa County (105 miles away) at 6.0% and Cherokee County (125 miles away) at 32.0%. 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 Pontotoc 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.

Pontotoc County, Geology
USGS's geologic map puts all of Pontotoc 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% |

Across Oklahoma 0.6% of the land is rated high; none of Pontotoc County's is. None of the 8 counties that border it has any moderate-potential ground either.
