Is Craven County, NC a radon risk area?

Craven County is mapped as Zone 3 - Low Potential by EPA — meaning the county-wide average indoor level is predicted below 2 pCi/L. Nationally that's the 26th percentile for radon potential — Craven County outranks 26% of every county EPA has rated.

How Craven County compares

About 104,167 people live in Craven County, North Carolina, spread over 706.541 square miles. Population density there runs about 147 people per square mile. Rank 213 by population within its EPA zone puts Craven County at the 79th percentile among zone peers. EPA's geology-based Region 4 groups Craven County with 735 other counties nationally sharing its underlying rock and soil profile.

Why the zone isn't the answer by itself

Craven 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 label describes Craven County's average, not any one basement or slab in it — testing is still the only way an individual homeowner actually finds out.

Next steps for a home in Craven County

Nothing about Craven County's EPA zone changes the mitigation number: $800–$2,500 nationally (around $1,200 typical), set by the house's foundation rather than the county it sits in — and only relevant once a test actually clears 4 pCi/L.
