What this actually means for a house in Larue County

Neither at the 4 pCi/L action level nor down at the roughly 1.3 pCi/L national indoor norm, Larue County's Zone 2 prediction lands in the gap between the two. Nothing about a Zone 2 label lowers the case for testing in Larue County — EPA recommends it in every zone, moderate included.

If Larue County tests above the action level

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.
