Is Nye County, NV a radon risk area?

EPA places Nye 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. Nationally that's the 56th percentile for radon potential — Nye County outranks 56% of every county EPA has rated.

How Nye County compares

About 55,990 people live in Nye County, Nevada, spread over 18,181.914 square miles. Population density there runs about 3 people per square mile.

Zone vs. an actual test

EPA's Zone 2 rating for Nye County sits below its own 4 pCi/L action level but above the national indoor average of about 1.3 pCi/L. A county-wide moderate average, like Nye County's, can still hide a specific house well above or below it — testing is what actually answers the question.

Next steps for a home in Nye County

Nothing about Nye 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.
