Compare your estimate with the cost calculatorPrimary state-level EPA reference: Zone 1. The ENTIRE state of Iowa is EPA Zone 1 — every single county. Iowa is considered one of the highest-risk states for radon in the United States.
EPA zone maps are county-level screening tools. Home-level testing is still required to confirm risk.
Iowa 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.
