Radon testing in Metro Detroit: what to expect
Radon is invisible and odorless, so testing is the only way to know your level. EGLE reports elevated radon in every Michigan county and expects about one in four Michigan homes to exceed the federal action level of 4 pCi/L. A test is the first step before any decision about mitigation.
Short-term tests run a few days in the lowest level you use as living space, with windows and doors kept closed; long-term tests give a better picture of the yearly average. Homeowners can use a do-it-yourself kit, and EGLE explains where to find one. Professional testing with a continuous radon monitor is common in real estate deals because it records readings over the whole test period.
Radon levels change as houses settle, so EGLE recommends retesting periodically. If your result is high, compare radon mitigation contractors. Buying a home? Ask your home inspection pro about adding a radon test.

Licensing and certification in Michigan
Radon testers are not licensed or regulated in Michigan, according to EGLE, which recommends choosing someone certified by the National Radon Proficiency Program (NRPP) or the National Radon Safety Board (NRSB). Ask for the certification and verify it with the certifying body.
For home sales, agree in writing who orders the test, where it is placed and how results will be shared. The Michigan Indoor Radon Program at EGLE also offers homeowner guidance and test kit information.
