Hooker County, NE: EPA's radon zone, explained

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

Hooker County by the numbers

Hooker County, Nebraska is home to about 698 people across 720.966 square miles. Population density there runs about 1 people per square mile.

What this actually means for a house in Hooker County

At Zone 3, Hooker County's predicted county average is under the national indoor average (~1.3 pCi/L) and well below EPA's 4 pCi/L action level — outdoor air nationally runs about 0.4 pCi/L for comparison. A Zone 3 rating means Hooker County's county-wide average is predicted low, but EPA is explicit that a meaningful share of homes in low-potential zones still test above the action level — a low zone is not a reason to skip testing.

Testing and mitigation in Hooker County

For a Hooker 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.
