Dickens County, TX: EPA's radon zone, explained

EPA's own radon map rates Dickens County zone 3 - low potential, predicting a county-wide average indoor level below 2 pCi/L. Dickens County sits at the 1st percentile nationally for radon potential — above 1 of every 100 rated counties.

Where Dickens County sits nationally

Dickens County, Texas is home to about 1,725 people across 901.724 square miles. Population density there runs about 2 people per square mile. By population, Dickens County is the 996th largest of every county sharing its EPA zone — the 3rd percentile by population within that zone. EPA's geology-based Region 6 groups Dickens County with 502 other counties nationally sharing its underlying rock and soil profile.

Why the zone isn't the answer by itself

Dickens 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. A Zone 3 rating means Dickens 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 Dickens County

For a Dickens 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.
