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 Clinton County's Zone 2 prediction. A county-wide moderate average, like Clinton County's, can still hide a specific house well above or below it — testing is what actually answers the question.
