In this study, the radiation exposure of workers at workplaces registered and licensed between 2008 and 2017 for the production/sale/use of radioactive isotopes (RI) and radioactive generators (RG) was analysed to evaluate the quality of radiation safety management controls in use. The number of facilities using RIs increased by ~26% from 2008 to 2017 whereas the number of facilities using RGs increased by ~166% over the same period. There were 33 029 radiation workers in all fields in 2008, and the number increased by ~32% to 43 467 by 2017. However, the collective effective dose of radiation received by workers decreased in all industries except for those working in nuclear power plants. In other words, the quality of radiation safety management improved over that same time period due to the systematic, continuous introduction of safety mechanisms by the regulatory authority.
在本研究中，对2008年至2017年期间注册并获得许可从事放射性同位素（RI）和放射性发生器（RG）生产/销售/使用的工作场所的工人的辐射暴露情况进行了分析，以评估所采用的辐射安全管理控制措施的质量。从2008年到2017年，使用RI的设施数量增加了约26%，而同期使用RG的设施数量增加了约166%。2008年所有领域共有33029名辐射工作人员，到2017年这一数字增加了约32%，达到43467名。然而，除核电站工作人员外，所有行业工人接受的集体有效辐射剂量均有所下降。换句话说，由于监管机构系统、持续地引入安全机制，同一时期的辐射安全管理质量得到了改善。
