本文介绍采用长短照射相结合的仪器中子活化分析法,测定了克山病病区、非病区的男性儿童头发中多种微量元素含量。比较了国内常用的及IAEA推荐的清洗方法对头发中微量元素测定的影响。用NBS标准参考物核对了实验中使用的部份标准,结果满意。本工作共分析了48例头发样品中27种元素含量,初步获得了某些元素在三个地区人发中分布的规律。 This article describes the use of a combination of length and shortness of exposure of the instrument neutron activation analysis of Keshan disease area, non-ward of the male children’s hair a variety of trace elements. The effects of domestic common and IAEA recommended cleaning methods on the determination of trace elements in hair were compared. The NBS standard reference material was used to check some of the standards used in the experiment, with satisfactory results. In this work, we analyzed the contents of 27 elements in 48 hair samples, and obtained the preliminary distribution of some elements in human hair in three regions.
