Lee County, AL: EPA's radon zone, explained

EPA's own radon map rates Lee County zone 2 - moderate potential, predicting a county-wide average indoor level between 2 and 4 pCi/L. That puts Lee County in the 62nd percentile nationally for radon potential — higher than 62% of the counties EPA has rated.

What this actually means for a house in Lee County

Neither at the 4 pCi/L action level nor down at the roughly 1.3 pCi/L national indoor norm, Lee County's Zone 2 prediction lands in the gap between the two. Lee County's Zone 2 rating sits in the middle nationally; EPA's guidance is unchanged by that — test every home regardless of its zone.
