Bangor 3D Shielding Plan.pdf

This is a shielding design specification sheet for Room 1404 Core Beam Dental Room at the Bangor VA facility, dated 11/8/22. The document details the required radiation shielding measurements for various barriers (doors, walls, and windows) in the dental room, with specifications given in millimeters of lead-equivalent protection. The barriers are designated A-B through L-M, each classified as "SECONDARY" protection type, with occupancy factors (OCC) ranging from 0.125 to 1, and distance factors (DIST) between 1.2 to 2.7. The required shielding thicknesses vary from 0.37 mm Pb to 1.33 mm Pb, with structural shielding equivalence measurements of 0.14 throughout, and recommended shielding additions ranging from 0.23 mm Pb to 1.24 mm Pb.
