前言放射性检查站的任务是通过测量各种容器中矿石的伽玛强度,从而确定该容器中矿石的铀含量,实现对矿石分选之目的。为达此目的,目前铀矿山放射性检查站均采用制作矿石标准源(已知含量),将它装在相应容器(汽车或矿车)中,作相对比较测量,从而获得换算系数值。即什么吨级运矿容器,就得有相应吨级的矿石标准源,并在一定间隔时间内进行测定。这样做,不仅劳动强度大,粉尘高,而且给工作带来很大的麻烦。
Foreword The mission of the radioactive checkpoint is to determine the uranium content of the ore in the container by measuring the gamma intensity of the ore in the various containers to achieve the purpose of sorting the ore. To this end, the current uranium mine radioactive checkpoints are used to produce the standard source of ore (known content), it is installed in the appropriate container (car or car), for comparative measurement, to obtain conversion factor values. That is, what ton of class Yun container, you have to have the corresponding standard ton of ore source, and measured at a time interval. In doing so, it is not only labor intensive and dusty, but also causes great inconvenience to work.
