Radon tests reported for Okmulgee County, 2008 to 2017, laboratory
CDC holds 1 reported test for Okmulgee County over the 2008 to 2017 laboratory totals, a result of 2.1 pCi/L: too few to describe a county (Radon411 reads a share from 30 tests up). Okmulgee County beside the counties around it is how this page reads it.
What these figures count
Only 1 test was reported to CDC for Okmulgee 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).
Okmulgee County, Compared
Okmulgee County radon figures, compared
Calculated by Radon411CDC's largest figure for Okmulgee County rests on 3 tests over the 2006 to 2015 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 2.1 pCi/L, with a middle value of 0.8 pCi/L.
Tulsa County, the one bordering county with a figure over the 2006 to 2015 laboratory totals, reported 6.0% of its tests at or above 4 pCi/L. Farther out, Cherokee County (57 miles away) at 32.0%, Washington County (74 miles away) at 11.3% and Oklahoma County (82 miles away) at 8.9% have figures too. 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 Okmulgee 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.
Okmulgee County, Geology
The ground under Okmulgee County
PredictedUSGS's geologic map puts all of Okmulgee 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% |

Okmulgee County, Cities and towns
Cities and towns in Okmulgee County
The Census Bureau estimates 37,241 residents in Okmulgee County for July 1, 2025, 553 more than in 2020 (+1.5%). That works out to 53 people per square mile of land. Okmulgee, the largest place on its list (11,394 residents in all), extends beyond Okmulgee County, so no share of the total is worked out for it. Reported testing is thin here: 3 tests over 2006 to 2015, or 0.1 for every 1,000 residents (2025 estimate), where Oklahoma as a whole comes to 0.2.
From Okmulgee to Hoffman, CDC publishes no figure by town: each reads Okmulgee County's.
