Analysis of radiological protection standard status for non-uranium mines in China / 中国职业医学

ABSTRACT

In China, the current effective special standards on radiological protection for non-uranium mines include GBZ 139-2019 Radiological Protection Requirements for the Production Places of Rare Earths, GBZ/T 233-2010 Radiological Protection Standards for the Workplaces of Tin Mine, and GBZ/T 256-2014 Radiological Protection Requirements for Radon Exposure in the Non-Uranium Mining. The above-mentioned special standards are applicable to all types of non-uranium mines except coal mines, and basically cover all aspects related to the practice of occupational exposure protection principles, such as responsibilities, workplace protection requirements, occupational exposure dose control, protective facilities and equipment, occupational exposure monitoring and evaluation, occupational health surveillance, and personnel training et al. However, there are differences in aspects such as workplace classification, individual dose monitoring and occupational health surveillance. According to the requirements of Chinese basic safety standard GB 18871-2002 Basic Standards for Protection Against Ionizing Radiation and for the Safety of Radiation Sources and international standards on occupational exposure protection, the hierarchical management in the workplace, occupational health management and radiological protection training of miners should be further improved, to provide suggestions and references for the formulation and revision of relevant standards for the prevention and control of occupational radiological diseases of non-uranium mine employees in China.
