Zone vs. an actual test

EPA's Zone 2 rating for Rusk County sits below its own 4 pCi/L action level but above the national indoor average of about 1.3 pCi/L. A county-wide moderate average, like Rusk County's, can still hide a specific house well above or below it — testing is what actually answers the question.

Next steps for a home in Rusk 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.
