Bedford County, PA radon potential
EPA places Bedford County in Zone 1 - Highest Potential — a predicted county-wide average indoor radon level above 4 pCi/L, based on the geology, soil and aerial radioactivity data behind EPA's national map. That puts Bedford County in the 90th percentile nationally for radon potential — higher than 90% of the counties EPA has rated.
Bedford County by the numbers
Bedford County, Pennsylvania is home to about 47,643 people across 1,011.99 square miles. That works out to roughly 47 people per square mile. Within its own EPA zone, Bedford County is bigger by population than 69% of the counties that share it. EPA's geology-based Region 3 groups Bedford County with 244 other counties nationally sharing its underlying rock and soil profile.
Why the zone isn't the answer by itself
Fixing a home becomes an EPA recommendation past 4 pCi/L, and that is precisely the side of the line Bedford County's Zone 1 prediction lands on, well above the roughly 1.3 pCi/L most US homes average. EPA's guidance doesn't change because of a Zone 1 label: test the house. What changes is the reason to not put it off in Bedford County specifically.
Next steps for a home in Bedford County
A short-term test kit is the standard first step and typically costs far less than mitigation itself. If a test comes back at or above 4 pCi/L, a radon mitigation system for a typical home runs roughly $800–$2,500 (around $1,200 for a common single-family install), driven mainly by foundation type, not by county.
