Tipper's take on radon in Ralston
Ralston is in Pawnee County, EPA Zone 3, the lowest risk classification. The EPA predicts average indoor radon levels below 2 pCi/L here. The CDC doesn't have enough test data from Pawnee County to calculate a reliable average. That means testing your own home is the only way to know.
Lower risk isn't no risk, though. Radon depends on your specific home's foundation, soil, and construction as much as county-level geology. Homes with basements or older foundations can test above 4 pCi/L even in Zone 3 areas.
Tipper's take: if you've never tested, a one-time check is cheap and quick. If you've already tested below 2 pCi/L, retest every two years or after any major renovation.
