摘　　要：考虑到工业γ射线探伤作业时产生电离辐射,文章基于探伤室投入运行后对周围剂量当量率的监测,根据运行后的监测结果进行评价。同时对工业γ射线探伤作业中的辐射安全问题展开讨论,旨在为工业γ射线的室内探伤项目建设及安全运行提供建议。In consideration of the ionizing radiation produced during the industrialγ-ray inspection,this paper selects a certain industrialγ-ray inspection room,estimates the material and thickness of the required shield through the theoretical mode,and evaluates whether the design parameters of the protection of the inspection room meet the radiation safety management requirements.Through monitoring the dose equivalent rate around the detection room after it is put into operation,and evaluating according to the monitoring results after operation.At the same time,the radiation safety problems in the industrialγ-ray inspection are discussed in order to provide suggestions for the construction and safe operation of the industrialγ-ray indoor inspection project.
