What these figures count
These are the 868 tests reported to CDC for Beaver 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).
Beaver County, Compared
Beaver County radon figures, compared
Calculated by Radon411In Beaver County, about 4 in 10 reported tests in 2020 (368 of 868) were at or above EPA's action level. Against the national pool of 25.5%, the gap is 16.9 points higher. Across 67 Pennsylvania counties pooled together, 30.3% of tests reached that level, so Beaver County runs 12.1 points above its state.
Of 4 neighbours with a figure, none reported a larger share at or above 4 pCi/L; the spread is 30.5% (Allegheny County) to 42.3% (Butler County). By share, Beaver County is 24th of 63 Pennsylvania counties with 30 or more tests for the same period.
Year by year, 2014 opened at 51.2% and 2020 closed at 42.4% (down 8.8 points), with 2014 the high at 51.2%. Half the tests came in under 3.2 pCi/L and half over it; the single highest reached 124.5 pCi/L. Below the action level, 270 tests (31.1%) came in under 2 pCi/L, against 44.3% statewide, and 230 tests (26.5%) fell between 2 and 4, against 25.4% statewide.
Zone 1 on EPA's map (predicted average above 4 pCi/L) and a 42.4% share point the same way here. USGS geology rates 100% of the county's land high radon potential.
The busiest year on file was 2014, with 1,075 tests reported; the quietest, 2017, had 756.
