某港口集装箱/车辆检查设备职业病危害放射防护预评价

Radiological Protection Evaluation of Occupational Hazards ofContainer/Vehicle Inspection Equipment

某港口配备组合移动式集装箱/车辆检查设备一套,为保障放射工作人员和可能进入该场所公众的辐射安全,对其进行了职业病危害放射防护预评价。依据国内外相关技术规范和标准,通过屏蔽防护计算、类比综合分析等方法进行评价,计算得出该集装箱/车辆检查系统各关注点的最大剂量当量率为2.44μSv/h;类比得出各关注点的最大剂量当量率为1.88μSv/h。研究表明,该集装箱/车辆检查系统屏蔽设计和防护设施符合国家法规和标准要求,正当使用该集装箱/车辆检查设备,能够有效保障放射工作人员和公众的辐射安全。

A port is equipped with a combined mobile container/vehicle inspection system to conduct radiation protection pre-assessment for occupational hazards in order to ensure radiation safety of radiation workers and the public who may enter the site.According to the national and international relevant technical standards and standards,through shielding protection calculation,analogical comprehensive analysis and other methods of evaluation.According to the calculation,the maximum dose of the container/vehicle inspection system is 2.44μSv/h.By analogy,the maximum dose at each point of the vehicle inspection system was 1.88μSv/h.The results of calculation and analogy show that the shielding design and protection facilities of the Container/Vehicle Inspection System meet the requirements of national regulations and standards.Proper use of the container/vehicle inspection system can effectively ensure the radiation safety of radiation workers and the public.
