Is Young County, TX a radon risk area?

Where Young County sits nationally

About 18,236 people live in Young County, Texas, spread over 914.498 square miles. Population density there runs about 20 people per square mile.

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

Why the zone isn't the answer by itself

Young County's predicted average sits below the national indoor average of about 1.3 pCi/L, well under EPA's 4 pCi/L action level. Don't read Zone 3 as a pass for Young County — EPA's guidance to test every home makes no exception for counties predicted low.
