Abstract
This paper describes how to use hand-held alpha and beta detectors to measure volume or mass contamination (Bq g-1) instead of the usual surface activity (Bq cm-2). As a proof of principle, measurements with a hand-held detector of the specific activity of K in potassium chloride yielded the expected result. Field measurements agree well with the results from analytical laboratories.
摘要
本文介绍了如何使用手持式α和β探测器来测量体积或质量污染（Bq g-1），而非通常的表面活度（Bq cm-2）。作为原理验证，用手持式探测器对氯化钾中钾的比活度进行测量得到了预期结果。现场测量结果与分析实验室的结果吻合良好。
