[en] The health physics programs for monitoring personnel at the UCC-ND facilities are designed to measure and record any amount of ionizing radiation doses received by employees. These measurements include both external and internal exposures that personnel might receive during normal routine job assignments as well as during any accidental radiation incident. This report, prepared at the Oak Ridge Y-12 Plant, summarizes current practices at the UCC-ND facilities to monitor personnel for external radiation exposure. It is principally a compilation that highlights material available in various forms within the four installations: Oak Ridge National Laboratory (ORNL), Oak Ridge Y-12 Plant (Y-12), Oak Ridge Gaseous Diffusion Plant (ORGDP), and Paducah Gaseous Diffusion Plant
