Fixing a home becomes an EPA recommendation past 4 pCi/L, and that is precisely the side of the line Shawano County's Zone 1 prediction lands on, well above the roughly 1.3 pCi/L most US homes average. EPA's guidance doesn't change because of a Zone 1 label: test the house. What changes is the reason to not put it off in Shawano County specifically.
