Measured: tests reported to CDC
CDC holds 3 reported tests for Beckham County over the 2008 to 2017 laboratory totals, with a median of 1.8 pCi/L: too few to describe a county (Radon411 reads a share from 30 tests up). Beckham County beside the counties around it is how this page reads it.
Only 3 tests were reported to CDC for Beckham 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.

Beckham County, Compared
CDC's largest figure for Beckham County rests on 5 tests over the 2006 to 2015 laboratory totals, 0 of them at or above 4 pCi/L, so each test moves its share by 20.0 points and no rank or comparison is drawn from it. Results reached as high as 2.3 pCi/L, with a middle value of 1.5 pCi/L.
The nearest counties with a figure are Oklahoma County (130 miles away) at 8.9%, Tulsa County (218 miles away) at 6.0% and Washington County (234 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 Beckham 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.

Beckham County, Geology
Most of the ground under Beckham County is one class on USGS's geologic map: 99.9% of its land is low radon potential, with 0.1% moderate. 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 | 99.9% |
