1 前言水是人们赖以生存的主要物质,质量的好坏直接影响着人的身体健康,随着生活水平的提高,以及放射性同位素的广泛应用,底比活度总α/β放射性的测量问题越来越多地受到关注。世界卫生组织1984年出版的《饮用水质量标准》和我国国家标准《地下水质量标准》(GB/T14848-93)中,总α/β放射性活度也是重要指标。目前,世界上各种测量方法不同,结果差别也较大。本文着重叙述了样品预处理、参数的确定和上机测
1 Introduction Water is the main material people rely on for survival. The quality of the product directly affects people’s health. With the improvement of living standards and the wide application of radioisotopes, the measurement of the total alpha / beta radioactivity of the base specific activity More and more attention. World Health Organization published in 1984, “drinking water quality standards” and our national standard “groundwater quality standards” (GB / T14848-93), the total α / β radioactivity is also an important indicator. At present, all kinds of measurement methods in the world are different, and the results are also different. This article focuses on the sample pretreatment, the determination of parameters and the machine measured
