辐射防护仪表.环境中放射性核素的测量.使用锗探测器的现场光子光谱测定系统

[中文适用范围]： 本国际标准适用于使用高纯锗 (HPGe) 探测器的便携式或可运输光子光谱测定装置，通常在地面以上 1m 处原位测量环境中离散放射性核素的区域。此类设备用于快速评估光子发射放射性核素的活动水平和相应的自由空气暴露率。此类测量可用于制定后续后续行动的指导，例如包括放射学评估、采样和监测计划。 （本标准不适用于单独标准涵盖的移动测量系统。请参阅 IEC 62438。） [外文原描述]： IEC 61275:2013 is applicable to a portable or transportable photon spectrometry assembly using a high purity germanium (HPGe) detector to survey, in situ, generally at 1 m above ground level, areas in the environment for discrete radionuclides. This standard specifies for such an assembly the general characteristics and test methods for evaluating radiation, electrical, mechanical, safety and environmental characteristics specific to the applications described above. Advice is also provided in annexes as to the calibration, appropriate use and interpretation of the system for in situ measurements. The main technical changes with regard to the previous edition are as follows: - encompass the latest technologies; - revise test methods to account for methodological developments and performance criteria with the latest HPGe detector technologies and digital electronics.
