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.
ABSTRACT
As compulsory standards in occupational health, the diagnostic criteria for occupational diseases are the main basis for the diagnosis of occupational diseases. According to the Occupation Disease Classification and Catalogue in China, there are currently 13 kinds of legal occupational radiation diseases in China. There are 14 supporting diagnostic criteria, including the GBZ 104-2017 Diagnosis of Acute Radiation Sickness from Occupational External Exposure, GBZ 99-2002 Diagnostic Criteria for Subacute Radiation Sickness from External Exposure, GBZ 105-2017 Diagnosis of Chronic Radiation Sickness from Occupational External Exposure, GBZ 96-2011 Diagnostic Criteria for Radiation Sickness from Internal Exposure, GBZ 106-2020 Diagnosis for Occupational Radiation Diseases of Skin, GBZ 97-2017 Judgment Standard for Occupational Radiogenic Neoplasms, GBZ 100-2010 Diagnostic Criteria for External Radiation Bone Injury, GBZ 101-2020 Diagnosis for Occupational Radiation Thyroid Disease, GBZ 107-2015 Diagnosis for Occupational Radiation Induced Gonad Disease, GBZ 102-2007 Diagnostic Criteria of Combined Radiation-blast Injury, GBZ 103-2007 Diagnostic Criteria of Combined Radiation-burn Injury, GBZ 95-2014 Diagnostic Criteria for Occupational Radiation Cataract, GBZ 108-2002 Diagnostic Criteria for Acute Uranium Intoxication and GBZ 112-2017 General Guideline for Diagnosis of Occupational Radiation Diseases. Compared with previous criteria, some of the new criteria changed a lot in terms of diagnostic conditions, included diseases, dose threshold and calculation methods for etiological probability. The science and practicability improved continually, which is conducive to standardize the diagnosis of occupational radiation diseases.
