In May 2021, a big accident occurred in Japan in which radiation workers were exposed to industrial X-ray. IAEA categorized this accident into Level 3 by the International Nuclear and Radiological Event Scale (INES). Considering the latest X-ray device conditions and accident examples, the Japanese authority has started to improve the national radiation control regulation for the use of industrial X-ray instruments. The authors are officially supporting the national movement as an expert team through their research. The authority is targeting the improvement on the structural standards for automatic warning and safety devices of X-ray equipment, the duties of X-ray safety supervisors, education and training for X-ray workers and supervisors, practical identification of controlled areas for X-ray equipment, and support for business operators and industry groups. The authors are especially focusing on safety education and training for X-ray workers and continue to survey the domestic and international status and situation supported by related stakeholders.The main scope of the authors' surveys is to compare the system of safety education and training on industrial X-rays and the way to manage industrial X-ray irradiators for safety in each country with the Japanese ones. The authors identified some countries had unique characteristics and found several differences depending on the country’s safety management history and culture: for example, regulatory system and competent ministries, categorization of equipment, requirements for initial and periodic education for workers, safety management of students, education and training content and time, requirements for safety supervisors, etc.The authors will show the latest results of the survey and Japanese future scope from the viewpoint of an expert team. The authors hope to discuss these topics with international safety experts and stakeholders from various countries at the venue, not only from the radiation field but the others. |
