EPA recommends action at 4.0 pCi/L, and many homeowners choose to reduce levels even below that threshold. Most of the Lower Peninsula is Zone 1, particularly the southeastern and central regions. The Upper Peninsula is mostly Zone 2. ZIP-level lookup tools are useful for local context, but home testing is still required.
