When to Test in Kansas City

Missouri 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.
