一种表面污染测量仪长期稳定性实验方法

对一台α、β表面污染测量仪进行长期稳定性检验。根据标准源和α、β表面污染测量仪探测窗的形状及尺寸设计制作标准源支架,并利用支架使标准源和探测窗的相对位置、距离保持固定,通过每隔一段时间用α、β表面污染测量仪读取一次标准源数据,获得质控数据。α、β表面污染测量仪的工作状态稳定可靠。通过制作放射源支架的方式,可以实现使用小于α、β表面污染测量仪探测面积的标准面源对α、β表面污染测量仪进行长期稳定性检验。

Objective For an α βSurface Contamination Dosimeter for long-term stability test. Method According to the standard source and α β Surface Contamination Dosimeter to detect the shape and size of the window design standard source support, and use the bracket to make standard source, detection and the relative position of the window, maintaining a constant distance, through every once in a while with alpha, beta, surface contamination measurement instrument read a standard source data, quality control data obtained. Result the working state of the α β Surface Contamination Dosimeter is stable and reliable. ConclusionThrough the way of production source support, can be achieved using less than α β Surface Contamination Dosimeter＇ s detection area standard of α β surface pollution from non-point sources measuring instrument for long-term stability test.
