Local Geology & Risk Factors
Doylestown is located in an area with Reading Prong / Triassic Lowland Transition geology, which contributes to elevated radon levels. The Pennsylvania DEP identifies this region as having significant radon potential due to uranium-bearing rock formations.
Testing is essential because radon levels can vary significantly between neighboring homes based on construction, soil permeability, and ventilation.
