Why the zone isn't the answer by itself

A Zone 3 county like Pittsburg County is predicted closer to the 0.4 pCi/L typical outdoors than to EPA's 4 pCi/L action level. Low doesn't mean zero: EPA's own data shows homes in Zone 3 counties like Pittsburg County testing above the action level often enough that skipping a test isn't the safe assumption.
