Why the zone isn't the answer by itself

Call it a middle case: above the 1.3 pCi/L most US homes average, below the 4 pCi/L line EPA uses to recommend mitigation — that's Gogebic County's Zone 2 prediction. Nothing about a Zone 2 label lowers the case for testing in Gogebic County — EPA recommends it in every zone, moderate included.
