Why the zone isn't the answer by itself

Where the national indoor average runs about 1.3 pCi/L, Dutchess County's Zone 1 rating puts its predicted county average above EPA's 4 pCi/L action level itself. A Zone 1 rating means testing is worth doing sooner rather than later, but it is still county-wide average, not a reading for any single house — some homes in Dutchess County will test well under the action level, and EPA's guidance is to test regardless of zone.
