Why the zone isn't the answer by itself

EPA's Zone 2 rating for Fulton County sits below its own 4 pCi/L action level but above the national indoor average of about 1.3 pCi/L. Middle-of-the-pack doesn't mean risk-free for any one Fulton County address — a moderate county average still leaves individual homes to test either side of it.

Testing and mitigation in Fulton County

A short-term test kit is the standard first step and typically costs far less than mitigation itself. If a test comes back at or above 4 pCi/L, a radon mitigation system for a typical home runs roughly $800–$2,500 (around $1,200 for a common single-family install), driven mainly by foundation type, not by county.
