What EPA's radon map says about Searcy County

EPA's own radon map rates Searcy County zone 2 - moderate potential, predicting a county-wide average indoor level between 2 and 4 pCi/L. That puts Searcy County in the 38th percentile nationally for radon potential — higher than 38% of the counties EPA has rated.

Where Searcy County sits nationally

About 7,836 people live in Searcy County, Arkansas, spread over 665.879 square miles. That works out to roughly 12 people per square mile.

EPA's geology-based Region 6 groups Searcy County with 502 other counties nationally sharing its underlying rock and soil profile.

Why the zone isn't the answer by itself

Neither at the 4 pCi/L action level nor down at the roughly 1.3 pCi/L national indoor norm, Searcy County's Zone 2 prediction lands in the gap between the two. Searcy County's Zone 2 rating sits in the middle nationally; EPA's guidance is unchanged by that — test every home regardless of its zone.
