采用监测γ辐射在后装治疗机机房及环境的45个分布点数值进行数据拟合处理，得到周围剂量当率三维空间分布图，并将其与国家相关标准《后装γ源治疗的患者防护与质量控制检测规范》数值进行对比，用来对后装机搬迁后新机房的放射防护性能和周围环境进行评价。

Theγ radiation in 45 distribution points of the breach-loading therapy machine room and its environment was monitored so as to perform the fitting process of monitoring data and obtain the 3D (Three Dimensional) spacial distribution map of the ambient dose equivalent rate. Then, comparisons were made between the monitoring data and national standards according to Prevention & Quality Control Test Standards for Patients Treated with Breach-Loadingγ Source to assess the radiation prevention performance of the new machine room of the breach-loading therapy machine and its surrounding environment.
