某DR机房整改前后周围环境辐射监测及分析
|
摘要
文章通过综合分析某DR(digital radiography)机房外辐射剂量率异常的原因,提出整改建议,并对整改前后机房周围辐射环境开展监测与评价,同时对实际工作中一些问题展开讨论,旨在为医学诊断X射线机项目建设及监管提供借鉴。
In this paper the causes of abnormal radiation dose rate outside a DR(digital radiography) machine room was comprehensively analyzed, the rectification suggestions were put forward, the radiation environment around the DR machine room before and after rectification was monitored and evaluated, and some problems in practical work were discussed, aiming to provide reference for the construction and supervision of medical diagnostic X-ray machine projects.
