Pennsylvania HB289 mandates radon testing in school buildings starting in the 2026-2027 school year.

Pennsylvania HB289 requires radon testing in all existing school buildings starting in the 2026-2027 school year. If radon levels are four picocuries per liter of air or higher, the building must be mitigated and retested until levels are below four picocuries per liter. New school buildings must be constructed using radon-resistant techniques. Initial testing must be conducted by a certified individual, and results reported within 60 days. Retesting intervals vary based on initial results, with higher levels requiring more frequent testing.
