摘　　要：对某选矿厂使用的核子称的放射源进行了调查。结果表明:在放射源工作状态下,在距铅室表面5cm、100cm及200cm的前、后、左、右、上及下方位的各监测点所监测到的辐射剂量当量率,各方位均符合国家标准限值要求。辐射剂量估计的结果完全达到国家标准要求。核子称具有计量准确、操作简便、使用安全可靠等优点,值得推广使用。In this paper,we investigated the radiation source of nucleon scale of which ore-dressing plant is using.The results shows that when the radiation source working,the radiant dose equivalent rate of every monitor points from Lead chamber's surface before and after,left and right within the each distance of 5 cm,100 cm,and 200 cm,are totally accord with the demands of the limit of the national standard.The estimated results are completely meeting to the demands of the limit of the national standard.The nucleon scale has the advantages of accurate measurement,simple operation,using safe and reliable and worth putting to use and popularizing.
