Why the zone isn't the answer by itself

Gordon County's Zone 3 prediction undercuts the roughly 1.3 pCi/L most US homes average, nowhere near EPA's 4 pCi/L threshold for recommending mitigation. Even at Zone 3, Gordon County homes are not guaranteed a low reading — zone is a county-wide average, and EPA recommends testing every home regardless of zone.
