How Beaver County compares

Beaver County’s median of 3.9 pCi/L ranks #31 of 67 Pennsylvania counties with CDC data. The middle Pennsylvania county median is 3.8 pCi/L, so Beaver County is above the state’s typical county. EPA puts the county in Zone 1, the highest-potential zone on EPA’s map (predicted average indoor level above 4 pCi/L).

These numbers come from tests homeowners and buyers chose to run, not a random survey. They show local risk; they cannot predict the level in your house.
