传统的表面污染监测主要是使用小型的表面污染探测仪器,探测效率低,涉及测点多,确定大面积的表面污染需要时间长,不能满足核应急的要求,为此,项目组开展了新型大面积表面污染监测装置研究,并于年内完成了装置的总体设计。但是,考虑到对于灵敏面积为上千平方厘米的表面污染监测装置,如果只关注灵敏区域内的平均活度,容易造成测量结果失真,进而导致小的污染热点探测不到。因此,在利用大面积闪烁体提
The traditional surface pollution monitoring mainly uses small surface contamination detection instruments. The detection efficiency is low, involving many measuring points. It takes a long time to determine large-area surface contamination and can not meet the requirements of nuclear emergency. Therefore, the project team launched a new large Area surface pollution monitoring device research, and completed the design of the device during the year. However, taking into account the sensitive area of surface contamination monitoring device for thousands of square centimeters, if you only focus on the average activity within the sensitive area, easily lead to distortion of the measurement results, resulting in small pollution hot spots undetectable. Therefore, the use of large-area scintillator mention
