Measured: tests reported to CDC
CDC holds 3 reported tests for Mayes County over the 2008 to 2017 laboratory totals, with a median of 3.8 pCi/L: too few to describe a county (Radon411 reads a share from 30 tests up). Mayes County beside the counties around it is how this page reads it.
Only 3 tests were reported to CDC for Mayes 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.

Mayes County, Compared
CDC's largest figure for Mayes County rests on 8 tests over the 2007 to 2016 laboratory totals, 1 of them at or above 4 pCi/L, so each test moves its share by 12.5 points and no rank or comparison is drawn from it. Results reached as high as 10.0 pCi/L, with a middle value of 1.3 pCi/L.
Of the counties bordering it, 2 have a figure over the 2006 to 2015 laboratory totals: Delaware County reported the largest share at or above 4 pCi/L, 44.7%, and Cherokee County the smallest, 32.0%. Farther out, Tulsa County (42 miles away) at 6.0%, Washington County (47 miles away) at 11.3% and Oklahoma County (133 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 Mayes County in Zone 2, its middle label: a predicted county average between 2 and 4 pCi/L. USGS geology rates 59% of the county's land low radon potential.

Mayes County, Geology
USGS's geologic map splits Mayes County: 58.8% of its land is low radon potential and 41.2% moderate. The map puts 58.8% of Mayes County in the area it calls Central Oklahoma Plains and Hills and 41.2% in Ozark Plateau. USGS gives the first a radon index of 7, in the low band (5 to 8), and the second 9, in the moderate band (9 to 11).
| 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 | 58.8% |
| Ozark Plateau | Mississippian and Pennsylvanian limestone and shale. | Moderate | 9 | 41.2% |
