What these figures count
These are the 123 tests reported to CDC for Wyoming County over 2020, many from homes being sold or already suspected of a problem: they describe the county's reported tests, not this house.
Measured: CDC tracking data. Figure above: 2020. Measured data period: 2005 to 2020 (every CDC figure on file).
Wyoming County, Compared
Wyoming County radon figures, compared
Calculated by Radon411In Wyoming County, about 3 in 10 reported tests in 2020 (38 of 123) were at or above EPA's action level. Against the national pool of 25.5%, the gap is 5.4 points higher. Across 67 Pennsylvania counties pooled together, 30.3% of tests reached that level, so Wyoming County runs 0.6 points above its state.
Of 5 neighbours with a figure, 2 reported a larger share at or above 4 pCi/L and 3 a smaller one; the spread is 27.1% (Lackawanna County) to 43.4% (Bradford County). By share, Wyoming County is 46th of 63 Pennsylvania counties with 30 or more tests for the same period.
Year by year, 2014 opened at 41.2% and 2020 closed at 30.9% (down 10.3 points), with 2017 the high at 44.0%. Half the tests came in under 2.0 pCi/L and half over it; the single highest reached 42.1 pCi/L. Below the action level, 58 tests (47.2%) came in under 2 pCi/L, against 44.3% statewide, and 27 tests (22.0%) fell between 2 and 4, against 25.4% statewide.
Zone 1 on EPA's map (predicted average above 4 pCi/L) and a 30.9% share point the same way here. USGS geology rates 100% of the county's land high radon potential.
The busiest year on file was 2019, with 191 tests reported; the quietest, 2014, had 97.

Wyoming County, Geology
The ground under Wyoming County
PredictedUSGS's geologic map puts all of Wyoming County's mapped land in one class: high radon potential. The map puts 48.4% of Wyoming County in the area it calls Glaciated Low Plateau Western Portion and 32.0% in Mountainous High Plateau, with one smaller area beside them. USGS gives the first a radon index of 13 and the second 12, both in the high band (12 to 17).
| Area | The rock, in USGS's words | Potential | Radon index | Share of land |
|---|---|---|---|---|
| Glaciated Low Plateau Western Portion | Moderately thick glacial till overlying sandstone, siltstone, mudstone, and shale. | High | 13 | 48.4% |
| Mountainous High Plateau | Sandstone, shale and conglomerate. | High | 12 | 32.0% |
| Appalachian Mountain Section | Paleozoic sandstone, shale, and limestone. | High | 12 | 19.6% |

Wyoming County beside the ground around it
Wyoming County has more high-potential ground than Pennsylvania as a whole: 100% of its land against 70.4%. Of the 5 counties that border it, none has as large a share of high-potential ground; Bradford County comes nearest at 100%.
