EPA Radon Zone Zone 1 — High Risk > 4.0 pCi/L (Zone 1)

County Branch County, MI

Zip Code 49255

Current radon submissions from Branch County are insufficient to establish local exposure patterns for this southern Michigan community. The region's glacial deposits over sedimentary bedrock can create variable radon conditions, particularly in homes with basements common to Michigan's residential architecture. Individual radon testing remains the most reliable method to assess specific property risk levels.
