Radon tests reported for Garvin County, 2008 to 2017, laboratory
CDC holds 1 reported test for Garvin County over the 2008 to 2017 laboratory totals, a result of 1.9 pCi/L: too few to describe a county (Radon411 reads a share from 30 tests up). Garvin County beside the counties around it is how this page reads it.
What these figures count
Only 1 test was reported to CDC for Garvin 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).
Garvin County, Compared
Garvin County radon figures, compared
Calculated by Radon411CDC's largest figure for Garvin County rests on 1 test over the 2008 to 2017 laboratory totals, 0 of them at or above 4 pCi/L, so each test moves its share by 100.0 points and no rank or comparison is drawn from it. Results reached as high as 1.9 pCi/L, with a middle value of 1.9 pCi/L.
The nearest counties with a figure are Oklahoma County (59 miles away) at 8.9%, Tulsa County (124 miles away) at 6.0% and Cherokee County (155 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 Garvin 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.

Garvin County, Geology
The ground under Garvin County
PredictedUSGS's geologic map puts all of Garvin 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% |

Garvin County beside the ground around it
Across Oklahoma 0.6% of the land is rated high; none of Garvin County's is. None of the 6 counties that border it has any moderate-potential ground either.
