What these figures count
Only 12 tests were reported to CDC for Curry County over 2022, 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: 2022. Measured data period: 2005 to 2022 (every CDC figure on file).
Curry County, Compared
Curry County radon figures, compared
Calculated by Radon411CDC's largest figure for Curry County rests on 19 tests in 2020, 1 of them at or above 4 pCi/L, so each test moves its share by 5.3 points and no rank or comparison is drawn from it. Results reached as high as 5.6 pCi/L, with a middle value of 0.9 pCi/L.
The nearest counties with a figure are Lane County (122 miles away) at 7.5%, Benton County (145 miles away) at 11.1% and Linn County (162 miles away) at 9.4%. Pooled across 35 Oregon counties, 21.5% of reported tests reached that level; across every county in the country with a figure, 31.2%.
Statewide for the same period, Union County reported the highest share (39.1%) and Deschutes County the lowest (6.7%). EPA's 1993 map puts Curry 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.

Curry County, Geology
The ground under Curry County
PredictedUSGS's geologic map puts all of Curry County's mapped land in one class: low radon potential. 98.5% of it lies in the area the map calls Klamath Mountains, 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 |
|---|---|---|---|---|
| Klamath Mountains | Triassic to Jurassic metamorphic, volcanic, and sedimentary rocks with some Cretaceous intrusive igneous rocks. | Low | 7 | 98.5% |
| Coast Range | Northern Coast Range is marine sedimentary rocks and Tertiary mafic volcanic rocks. Southern Coast Range is Tertiary estuarine and marine sedimentary rocks, feldspathic and micaceous. | Low | 7 | 1.2% |

Curry County beside the ground around it
Across Oregon 62.3% of the land is rated moderate; none of Curry County's is. None of the 4 counties that border it has any moderate-potential ground either.
