摘要
采用放射性核素中子源的中子参考辐射装置不仅可用于中子防护仪表日常校准、刻度,还可以作为硬件平台开展部分实验研究。中国计量科学研究院根据ISO 8529—1的规定以及中子参考辐射装置的用途,对原有的中子参考辐射装置进行了技术改造,使其不仅满足中子防护仪表日常校准的要求,同时也可满足部分中子实验的要求。
Abstract
The reference radiations produced by radionuclide neutron sources can be used in routine calibration or scaling of the neutron survey meter, it also can be used as the basis platform of some experiments.The neutron reference radiation facility in the National Institute of Metrology is improved according to the ISO 8529—1 and the purposes of the facility.The facility fulfilled with the requirements of routine calibration for neutron instruments, and it can be used for the experiments for evaluating the neutron detectors and neutron protective materials.
