Radon Levels in Missaukee County, Michigan

EPA puts Missaukee County in Zone 3, its lowest radon zone, and most reported tests there come back low, though 14.9% of 350 (2008 to 2017, laboratory totals) reached 4 pCi/L. Homes with elevated levels occur in all three zones, so only a test measures yours.

Missaukee County, Compared

Missaukee County radon figures, compared

Calculated by Radon411

Missaukee County reports fewer high tests than Michigan overall. 14.9% of its 350 tests over the 2008 to 2017 laboratory totals were at or above 4 pCi/L. That is 12.0 points below the 26.9% pooled from 83 Michigan counties.

Ordered from highest share down, it comes 52nd 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%; Missaukee County sits 20.8 points below it.

Next door, the shares run from 6.2% in Crawford County to 14.1% in Clare County, with Clare County, Roscommon County and Kalkaska County below Missaukee County. Zone 3 on EPA's map (predicted average under 2 pCi/L) and a 14.9% share point the same way here.

Half the tests came in under 1.6 pCi/L and half over it; the single highest reached 12.9 pCi/L. The rest split 59.7% under 2 pCi/L and 25.4% from 2 to 4 (Michigan: 46.4% and 26.7%).

CDC's ten-year totals for Missaukee County went from 426 tests (2005 to 2014) to 350 (2008 to 2017), the share going from 11.7% to 14.9%.
