Zone vs. an actual test

Mecklenburg County's predicted average falls between EPA's 4 pCi/L action level and the national indoor average of about 1.3 pCi/L (outdoor air runs roughly 0.4 pCi/L). A Zone 2 rating is a moderate county-wide average, not a guarantee about any one house in Mecklenburg County — testing is the only way to know an individual home's actual level.

If Mecklenburg County tests above the action level
