Price County, Compared

Price County radon figures, compared

Calculated by Radon411

In Price County, about 4 in 10 reported tests in 2023 (22 of 60) were at or above EPA's action level. Against the national pool of 33.4%, the gap is 3.3 points higher. Across 72 Wisconsin counties pooled together, 35.7% of tests reached that level, so Price County runs 1.0 points above its state.

Of 7 neighbours with a figure, 3 reported a larger share at or above 4 pCi/L and 4 a smaller one; the spread is 18.9% (Taylor County) to 42.6% (Sawyer County). By share, Price County is 39th of 69 Wisconsin counties with 30 or more tests for the same period.

Year by year, 2015 opened at 40.4% and 2023 closed at 36.7% (down 3.7 points), with 2016 the high at 53.4%. Half the tests came in under 2.8 pCi/L and half over it; the single highest reached 16.2 pCi/L. Below the action level, 19 tests (31.7%) came in under 2 pCi/L, against 41.4% statewide, and 19 tests (31.7%) fell between 2 and 4, against 23.0% statewide.

Zone 2 on EPA's map (predicted average between 2 and 4 pCi/L) and a 36.7% share point the same way here. USGS geology rates 100% of the county's land moderate radon potential.

The busiest year on file was 2017, with 78 tests reported; the quietest, 2021, had 13.

Share of reported tests at or above 4 pCi/L by year, Price County against Wisconsin2015 to 2023, years with 30 or more tests: Price County 40.4% to 36.7%, the state's pooled share 35.7% in 2023.

The ground under Price County

Predicted

USGS's geologic map puts all of Price County's mapped land in one class: moderate radon potential. All of it lies in the area the map calls Chippewa, Wisconsin Valley, and Langlade sublobes of the Superior Lobe, to which USGS gives a radon index of 10, in the moderate band (9 to 11).
