Radon Mitigation in Gettysburg
High radon risk from the Gettysburg Basin's Triassic sedimentary rocks and diabase intrusions. Adams County sits on a complex of Triassic shale, siltstone, and diabase sills where uranium is concentrated at contact zones between igneous intrusions and surrounding sedimentary rock. The Gettysburg diabase — a dense, dark rock visible in the battlefield landscape — weathers to produce uranium-enriched soils.
