The EPA places Knox County in radon zone 2, a predicted average indoor radon screening level from 2 to 4 pCi/L. The zone is a screening prediction for the county and does not substitute for a test at an address. 25.0 percent of the county's listed communities participate in the National Flood Insurance Program, per Federal Emergency Management Agency, NFIP Community Status Book (OpenFEMA), as of 2026-09-26.
