Loup County, NE: EPA's radon zone, explained
EPA's own radon map rates Loup County zone 3 - low potential, predicting a county-wide average indoor level below 2 pCi/L. That puts Loup County in the 0th percentile nationally for radon potential — higher than 0% of the counties EPA has rated.

Why the zone isn't the answer by itself
Loup County's Zone 3 prediction undercuts the roughly 1.3 pCi/L most US homes average, nowhere near EPA's 4 pCi/L threshold for recommending mitigation. Don't read Zone 3 as a pass for Loup County — EPA's guidance to test every home makes no exception for counties predicted low.
If Loup County tests above the action level
For a Loup County homeowner, the order is simple: test first, since a kit costs a small fraction of what mitigation would. Only if the result clears 4 pCi/L does a system — typically $800–$2,500, about $1,200 for a common install — become worth pricing out.
