Texas County, OK: EPA's radon zone, explained

EPA places Texas County in Zone 2 - Moderate Potential — a predicted county-wide average indoor radon level between 2 and 4 pCi/L, based on the geology, soil and aerial radioactivity data behind EPA's national map. That puts Texas County in the 46th percentile nationally for radon potential — higher than 46% of the counties EPA has rated.

How Texas County compares

Texas County, Oklahoma is home to about 20,577 people across 2,041.293 square miles. That works out to roughly 10 people per square mile. By population, Texas County is the 617th largest of every county sharing its EPA zone — the 40th percentile by population within that zone. EPA's geology-based Region 6 groups Texas 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, Texas County's Zone 2 prediction lands in the gap between the two. A county-wide moderate average, like Texas County's, can still hide a specific house well above or below it — testing is what actually answers the question.

Testing and mitigation in Texas County

For a Texas 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.
