- Abstract: Neither NCRP Report 147, Structural Shielding Design for Medical X-Ray Imaging Facilities nor NCRP Report 151, Structural Shielding Design and Evaluation for Megavoltage X- and Gamma-Ray Radiotherapy Facilities addresses brachytherapy facility shielding. This presentation reviews new shielding data (TVLs) for 103Pd, 131Cs, 169Yb, 170Tm (Thulium), and 192Ir, reviews typical workloads for high-dose-rate (HDR) facilities, compares textbook recommended HDR vault shielding designs to those recently reported in the literature, and investigates HDR maze scatter using the methodology described in NCRP 151 for linear accelerators. The data and subsequent representative calculations represent the current state-of-the-art of brachytherapy facility shielding.
