Tipper's take on radon in Staten Island
Staten Island is in Richmond County, EPA Zone 3, the lowest risk classification. The EPA predicts average indoor radon levels below 2 pCi/L here. CDC data from Richmond County puts the average measured radon level at 1.8 pCi/L.
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.
