EPA Radon Levels
Pennsylvania has 67 counties and 49 (73%) have been assigned Zone 1 counties by the EPA. Zone 1 counties have the highest potential to have homes test higher than 4 pCi/L. Pennsylvania's state radon zone average is 1.28, which is the average of all county zone ratings the EPA has assigned the state, ranking it 9 among all states.
The radon levels in Pennsylvania are above average in many areas of the state. More than 61% of all homes tested in the state have been found to have elevated radon levels above the EPA recommended action level. There’s an increased risk for all homeowners, which is why we recommend testing exposure levels at least twice a year.
