IEEE N42.31-2003 pdf free.American National Standard for Measurement Procedures for Resolution and Efficiency of Wide-Bandgap Semiconductor Detectors of Ionizing Radiation. Abstract: Standard measurement and test procedures are established for wide-bandgap semiconductor detectors such as cadmium telluride (CdTe), cadmium-zinc-telluride (CdZnTe), and mercuric iodide (Hgl2) that can be used at room temperature for the detection and quantitative characterization of gamma-rays, X-rays, and...
