近年来,世界各地的恐怖活动极为频繁,给世界各国人民的生命财产造成极大的威胁。在无损检测方面,与传统检测方法比较,中子技术更可靠有效。但中子穿透力很强,实验工作人员受到超标准剂量照射时,将对人身造成一定的伤害。为了确保人员的安全,必须做好工作人员的防护。本工作针对中国原子能科学研究院核技术应用研 In recent years, the terrorist activities around the world have been extremely frequent, posing a tremendous threat to the lives and property of the people of all countries in the world. In non-destructive testing, compared with the traditional detection methods, neutron technology is more reliable and effective. However, the penetrating power of neutrons is very strong. When the laboratory staff is exposed to an excessive standard dose of radiation, it will cause some harm to the human body. In order to ensure the safety of personnel, staff protection must be well done. This work is aimed at the nuclear technology application research of China Institute of Atomic Energy
