Radon testing & mitigation in Allentown, PA

Allentown sits in Lehigh County. In the PA DEP test dataset, 29,724 basement radon tests carry a Allentown address. Their median was 3.6 pCi/L, and 47% came in at or above EPA's 4 pCi/L action level. Across all of Lehigh County it was 47%, and statewide 37%. Even where the average is lower, neighboring houses can test very differently, so every home should be tested.
