Why the zone isn't the answer by itself

Well clear of both the 1.3 pCi/L national indoor average and EPA's 4 pCi/L action level, Woodruff County's Zone 3 prediction is the low end of the scale. Even at Zone 3, Woodruff County homes are not guaranteed a low reading — zone is a county-wide average, and EPA recommends testing every home regardless of zone.
