Beckham County by the numbers

Beckham County, Oklahoma is home to about 22,248 people across 901.675 square miles. Population density there runs about 25 people per square mile.

Why the zone isn't the answer by itself

At Zone 3, Beckham 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. Don't read Zone 3 as a pass for Beckham County — EPA's guidance to test every home makes no exception for counties predicted low.

Testing and mitigation in Beckham County

A short-term test kit is the standard first step and typically costs far less than mitigation itself.
