Radon Levels in Wexford County, Michigan
EPA puts Wexford County in Zone 3, its lowest radon zone, and most reported tests there come back low, though 9.7% of 621 (2008 to 2017, laboratory totals) reached 4 pCi/L. Homes with elevated levels occur in all three zones, so only a test measures yours.

Wexford County, Compared
Wexford County radon figures, compared
Calculated by Radon411Wexford County reports fewer high tests than Michigan overall. 9.7% of its 621 tests over the 2008 to 2017 laboratory totals were at or above 4 pCi/L. That is 17.2 points below the 26.9% pooled from 83 Michigan counties.
Ordered from highest share down, it comes 70th of 82 Michigan counties with 30 or more tests for the same period. Nationally, every county with a figure for the same period pools to 35.7%; Wexford County sits 26.0 points below it.
Next door, the shares run from 8.7% in Benzie County to 16.5% in Manistee County, with Benzie County below Wexford County. Zone 3 on EPA's map (predicted average under 2 pCi/L) and a 9.7% share point the same way here.
Half the tests came in under 1.5 pCi/L and half over it; the single highest reached 12.2 pCi/L. The rest split 61.0% under 2 pCi/L and 29.3% from 2 to 4 (Michigan: 46.4% and 26.7%).
CDC's ten-year totals for Wexford County went from 715 tests (2005 to 2014) to 621 (2008 to 2017), the share going from 10.1% to 9.7%.

- EGLE's figures cover first-time tests only, from organizations willing to provide data.
- EGLE does not publish figures for a ZIP code with fewer than 5 test results.
- EGLE says the map is not intended to decide whether a home should be tested: all homes should be tested.
- ZIP code boundaries are postal delivery areas, not legal or administrative boundaries.
- A ZIP code that crosses the county line is listed whole; its figures cover all of it.
