Radon Testing in Madeira, OH

Radon Testing in Madeira involves short-term (2-7 day) charcoal canister or continuous radon monitor placement on the lowest occupied level, working on the lowest lived-in level of the home where occupants spend more than 4 hours per day. The service is the first step for any home that has not been tested in the last 2 years, for any home being sold, and for any home after a significant foundation, basement, or HVAC modification.

Madeira's owner stock is mostly 1950s-1970s ranch and split-level with drywall walls, vented attics, and crawl spaces or partial basements. Original R-11 fiberglass batts are common in both attic and wall cavities; rim joists are typically uninsulated. Madeira sits on the Cincinnati Arch geology (fractured Ordovician limestone and shale) that drives elevated regional radon exposure across the entire Greater Cincinnati metro, including Hamilton County.

ANSI/AARST MAH-2023 establishes the residential measurement protocol. Closed-house conditions must be maintained throughout short-term testing. The Ohio Department of Health Radon Licensing Program oversees radon program compliance for Madeira, and Ohio licensure under ORC 3723.02 applies to any contractor performing mitigation work in the state.
