Radon Levels in Cheboygan County, Michigan
EPA puts Cheboygan County in Zone 3, its lowest radon zone, and most reported tests there come back low, though 8.0% of 465 (2008 to 2017, laboratory totals) reached 4 pCi/L. Homes with elevated levels occur in all three zones, so only a test measures yours.

Next door, the shares run from 9.8% in Charlevoix County to 38.2% in Otsego County. Zone 3 on EPA's map (predicted average under 2 pCi/L) and a 8.0% share point the same way here.
Half the tests came in under 0.8 pCi/L and half over it; the single highest reached 20.8 pCi/L. The rest split 77.2% under 2 pCi/L and 14.8% from 2 to 4 (Michigan: 46.4% and 26.7%).
CDC's ten-year totals for Cheboygan County went from 496 tests (2005 to 2014) to 465 (2008 to 2017), the share going from 7.5% to 8.0%.

|---|---|---|---|---|
| Glacial lakes | Silt and clay glacial lake deposits. | Low | 7 | 59.0% |
| Antrim Shale | Glacial deposits dervied in part from Antrim black shale. | Moderate | 10 | 40.9% |
