Why the zone isn't the answer by itself

Well clear of both the 1.3 pCi/L national indoor average and EPA's 4 pCi/L action level, Wilcox County's Zone 3 prediction is the low end of the scale. Don't read Zone 3 as a pass for Wilcox County — EPA's guidance to test every home makes no exception for counties predicted low.

Testing and mitigation in Wilcox 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.
