Abstract:
Objective To evaluate the current status of radioactive occupational hazards in the construction of some medical institutions in Tianjin, discover existingproblems and deficiencies, and provide a technical basis for radiation protection management. Methods Based on the requirements of relevant regulations and standards, we comprehensivelyevaluated the results of the pre-evaluation and control effect evaluation of 81 radioactive occupational hazards in Tianjin. Results Among the 35 proposed protective measures for pre-evaluation of radiation occupational hazards constructionprojects, the lowest compliance rate is warning signs and personal protective equipment. Among the 46 construction projects of radioactive occupational hazard control evaluation, the pass rate of protective measures was between 73.9% and 100%, with the lowest pass rate for personal protective equipment. Besides, the pass rate of radiation protectionmanagement evaluation was 95.7% ～ 100%, with the lowest pass rate for the protection management system.The initial inspectionpass rateof the equipment quality control acceptancewas 98.6%, while the pass rate was 97.1% for the relevant workplace radiation protection during the initial inspection. Conclusion The pre-evaluation completion rate of radiological occupational hazard evaluation in Tianjin medical institution construction project, unilateral and area of construction room, workplace layout and zoning, ventilation, shielding measures, personal dose management and occupational health inspection all meet the requirements of regulations and standards. However, there are still some deficiencies in the personal protective equipment, warning signs and the radiation protection management system. Therefore, the regulatory department should further strengthen the evaluation of medical institutions, especially the key supervision and management of non-conformities.
