Radon Levels in Luce County, Michigan

EPA Zone 3: lower predicted potential

is EPA's lowest class, and its forecast for Luce County as a whole is an average indoor of less than 2 pCi/L (less than 75 Bq/m³). A low zone clears no address in it: homes above EPA's turn up in all three zones.

Measured: tests reported to CDC

Radon tests reported for Luce County, 2008 to 2017, laboratory

CDC holds 24 reported tests for Luce County over the 2008 to 2017 laboratory totals, with a median of 1.0 pCi/L: too few to describe a county (Radon411 reads a share from 30 tests up). Luce County beside the counties around it is how this page reads it.

What these figures count

Only 24 tests were reported to CDC for Luce County over 2008 to 2017 (laboratory totals), and tests are often run on homes being sold or already suspected of a problem: so few describe neither the county nor this house.

Measured: CDC tracking data. Figure above: 2008 to 2017, laboratory. Measured data period: 2005 to 2017 (every CDC figure on file).

Luce County, Compared

Luce County radon figures, compared

Calculated by Radon411

Only 3 of 64 radon tests reported for Luce County over the 2005 to 2014 laboratory totals reached 4 pCi/L (4.7%). The median result, 0.9 pCi/L, sits below 2, well under EPA's 4 pCi/L action level, and the top reported result was 10.9 pCi/L.

The newest figure, over the 2008 to 2017 laboratory totals, counts only 24 tests (4.2% at or above 4 pCi/L), too few to compare, so this reading uses the 64-test figure.

Across 83 Michigan counties pooled together, 26.2% of tests reached that level, so Luce County runs 21.5 points below its state. Against the national pool of 36.0%, the gap is 31.3 points lower. Its place in the state: 81st of 83 Michigan counties with 30 or more tests for the same period.

Zone 3 on EPA's map (predicted average under 2 pCi/L) and a 4.7% share point the same way here. Of 4 neighbours with a figure, all 4 reported a larger share at or above 4 pCi/L; the spread is 9.2% (Schoolcraft County) to 18.8% (Mackinac County).

Below the action level, 53 tests (82.8%) came in under 2 pCi/L, against 48.1% statewide, and 8 tests (12.5%) fell between 2 and 4, against 25.6% statewide. USGS geology rates 100% of the county's land low radon potential.

CDC's ten-year totals for Luce County went from 64 tests (2005 to 2014) to 24 (2008 to 2017), the share going from 4.7% to 4.2%.

What Michigan EGLE reports for the ZIP codes in Luce County

Michigan EGLE publishes its figures by ZIP code, not by county. These are the 2 ZIP codes that lie wholly or partly in Luce County, each with the state's own figures for it. Period: About 10 years to 2026-05-15.

  • 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.
