Why York County homeowners take radon seriously

York County's Piedmont geology — carbonate bedrock in the lowlands, slate and schist in the uplands — is exactly the kind of terrain the U.S. Geological Survey links to elevated indoor radon across Pennsylvania. A state-run EPA/PA survey of 68 York County homes found an average indoor radon level of 15.5 pCi/L, with 68% of homes tested above the EPA's 4 pCi/L action level. Radon is colorless and odorless — testing is the only way to know where your home stands. See the full picture on York County radon levels.
