Compare your estimate with the cost calculatorEPA Zone / County Risk
Primary state-level EPA reference: Zone 1. The majority of Ohio counties are Zone 1, particularly northeastern and central regions. Ohio has one of the most widespread radon problems in the US.
EPA zone maps are county-level screening tools. Home-level testing is still required to confirm risk.
When to Test in Dayton
Ohio 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.
