What EPA's radon map says about Wood County

That puts Wood County in the 59th percentile nationally for radon potential — higher than 59% of the counties EPA has rated.

Zone vs. an actual test

Neither at the 4 pCi/L action level nor down at the roughly 1.3 pCi/L national indoor norm, Wood County's Zone 2 prediction lands in the gap between the two. A Zone 2 rating is a moderate county-wide average, not a guarantee about any one house in Wood County — testing is the only way to know an individual home's actual level.
