What this actually means for a house in Bossier Parish

Well clear of both the 1.3 pCi/L national indoor average and EPA's 4 pCi/L action level, Bossier Parish's Zone 3 prediction is the low end of the scale. Low doesn't mean zero: EPA's own data shows homes in Zone 3 counties like Bossier Parish testing above the action level often enough that skipping a test isn't the safe assumption.

If Bossier Parish 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.
