Paulding County, OH: EPA's radon zone, explained
EPA places Paulding 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. That puts Paulding County in the 45th percentile nationally for radon potential — higher than 45% of the counties EPA has rated.
Paulding County by the numbers
Paulding County, Ohio is home to about 18,755 people across 416.436 square miles. Population density there runs about 45 people per square mile. By population, Paulding County is the 646th largest of every county sharing its EPA zone — the 37th percentile by population within that zone. EPA's geology-based Region 5 groups Paulding County with 523 other counties nationally sharing its underlying rock and soil profile.
What this actually means for a house in Paulding County
Neither at the 4 pCi/L action level nor down at the roughly 1.3 pCi/L national indoor norm, Paulding County's Zone 2 prediction lands in the gap between the two. Middle-of-the-pack doesn't mean risk-free for any one Paulding County address — a moderate county average still leaves individual homes to test either side of it.
Testing and mitigation in Paulding County
For a Paulding 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.
