Abstract: By investigating the publications, standards and documents related to the regulation of occupational disease hazards in the decommissioning of nuclear facilities, this paper analyzes the types, characteristics and regulatory status of occupational disease hazards in the process of decommissioning of nuclear facilities. It is considered that compared with the normal operation stage and building construction operations, the decommissioning of nuclear facilities has the characteristics of complex radiation source terms, strong radioactivity, uneven distribution of environmental radiation field, prominent dust hazard factors, etc, Its occupational disease hazard regulation measures are similar to construction operations, and it is difficult to regulate occupational disease hazards. Whether it is normal decommissioning or post-accident decommissioning, the health risks faced by workers participating in the decommissioning of nuclear facilities are still a key concern of all countries. In view of this, China should, on the basis of IAEA and domestic decommissioning related operating experience, combined with the characteristics of Nuclear Facility Decommissioning and the current situation of occupational hazard management, put forward prevention and management measures for occupational disease hazards at the decommissioning site of nuclear facilities in China, so as to provide occupational health regulation basis for the growing nuclear facility decommissioning project in China, and promote the healthy and stable development of Nuclear Facility Decommissioning in China.

Key words: decommissioning of nuclear facilities, occupational hazards, regulation
