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