Tennessee includes EPA Zone 1 counties, so radon mitigation in Old Hickory should be treated as a core indoor-air priority. 1 local contractor is currently listed, so broader metro comparisons may help with pricing and availability. Based on EPA county-level mapping, Tennessee includes Zone 1 areas, which indicates high predicted indoor radon potential. State context: Knox County (Knoxville) has some of the highest average radon levels in Tennessee. The combination of Appalachian geology, limestone karst bedrock, and valley topography that traps soil gases creates ideal conditions for elevated indoor radon across east Tennessee.

Compare your estimate with the cost calculatorPrimary state-level EPA reference: Zone 1. East Tennessee is Zone 1 with high radon risk — Knox, Anderson, Blount, and surrounding counties regularly test well above 4.0 pCi/L. Middle Tennessee including Nashville is Zone 2 with moderate risk. West Tennessee including Memphis is Zone 3 with generally lower levels.
EPA zone maps are county-level screening tools. Home-level testing is still required to confirm risk.
Tennessee is generally mapped as higher-potential radon territory (Zone 1), so annual-to-biannual testing is common after mitigation or major foundation changes. For seasonal timing, closed-house winter testing usually captures worst-case indoor buildup. For real-estate transactions, run a short-term test during due diligence, then confirm with follow-up testing if results are near or above 4.0 pCi/L.
