Short answer: the median radon test in Bucks County was 2.1 pCi/L (CDC, lab tests 2008 to 2017). That is under EPA’s action level of 4 pCi/L but in the 2 to 4 range where EPA suggests considering a fix. Because it is a median, many homes in the county tested higher.
How Bucks County compares
Bucks County’s median of 2.1 pCi/L ranks #64 of 67 Pennsylvania counties with CDC data. The middle Pennsylvania county median is 3.8 pCi/L, so Bucks County is below 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.
