TY - BOOK ID - 14226679 TI - ANSI/IEEE Std 680-1978 : IEEE Standard Techniques for Determination of Germanium Semiconductor Detector Gamma-Ray Efficiency Using a Standard Marinelli (Reentrant) Beaker Geometry PY - 1978 SN - 1504404173 PB - [Place of publication not identified] : IEEE, DB - UniCat KW - Gamma rays. UR - https://www.unicat.be/uniCat?func=search&query=sysid:14226679 AB - This standard for determination of gamma-ray efficiencies of germanium semiconductor detectors was developed in recognition of the increasing number of large-volume, low-activity samples being measured by gamma-ray spectroscopy. The standardized sample geometry and measurement techniques described, when used in conjunction with the relative efficiency measurement standard ANSI/IEEE Std 325-1971 (Reaff 1977), Test Procedures for Germanium Gamma-Ray Detectors, provide a meaningful assessment of detector performance. It is recognized that many Marinelli beaker geometries are in use. However, the object of this standard is to specify a single configuration for the sole purpose of characterizing detector performance. ER -
