Title: Technical Evaluation of Electrically Cooled Detectors for use with the LLNL Whole Body Scanning Bed System

Abstract

Lawrence Livermore National Laboratory (LLNL) is replacing a liquid nitrogen cooled high purity germanium detection system with an electrically cooled high purity germanium system for its scanning bed whole body counting system. The new detectors offer a safer environment for workers while they are measured inside the shielded facility at LLNL and provide highly stable cooling of the detectors. The positioning of the electrically cooled detectors is slightly different from the liquid nitrogen cooled detectors due to the electrical cooling units attached to the detectors. The technical evaluations and results described in this document demonstrate that the new electrically cooled system provides results that comply with internal dosimetry requirements
