Why the zone isn't the answer by itself

EPA's Zone 2 rating for Bailey County sits below its own 4 pCi/L action level but above the national indoor average of about 1.3 pCi/L. Bailey County's Zone 2 rating sits in the middle nationally; EPA's guidance is unchanged by that — test every home regardless of its zone.
