摘要
目的对某医院PET/CT中心建设项目放射防护控制效果评价阶段平面布局方面存在的问题进行分析与评价,并提出职业病危害放射防护评价工作,特别是预评价工作的重要性。方法在现场核实的基础上,依据相关的法律、法规和标准,对某PET/CT工作场所布局进行分析与评价。结果该PET/CT中心平面布局存在不合理之处,包括:场所布局未按从低活性区向高活性区布置,未设置卫生通过间,未设置放射性药物和废物运输专用通道。结论核医学工作场所合理的布局是保证其放射防护最优化的前提,职业病危害放射防护预评价是决定其布局是否合理的关键。
Objective To analyze and evaluate the problems existing in the plane layout of radiation protection control effect evaluation stage of a hospital PET/CT center construction project, and to propose the importance of occupational hazard radiation protection evaluation, especially the pre-evaluation. Method The layout of the PET/CT workplace was analyzed and evaluated on the basis of on-site verification and in accordance with relevant laws, regulations and standards. Results The layout of the PET/CT center was unreasonable, including: the site layout was not arranged from the low activity area to the high activity area, the sanitary passage was not set, the dedicated channel for transport of radioactive drugs and waste was not set. Conclusion The reasonable layout of nuclear medicine workplace is the premise to ensure the optimization of radiation protection, and the pre-evaluation of occupational hazard radiation protection is the key to determine whether the layout is reasonable or not.
