What this actually means for a house in Etowah County

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 Etowah County's Zone 2 prediction. Middle-of-the-pack doesn't mean risk-free for any one Etowah County address — a moderate county average still leaves individual homes to test either side of it.
