摘　　要：详细介绍和评述了环境和生物样品中低水平放射性核素90Sr的放射化学分析方法,从样品前处理、化学分离以及检测方法3个方面综述了国内外的标准方法以及最新研究进展情况。建议进一步完善我国标准方法,建立适应于核辐射事故应急情况下的快速分析方法。This paper presents a review on the method of radiochemical analyses, including samples pretreatment, chemical separation and counting, for the determination of low-level 90Sr in environmental and biological samples. The recommended standard methods in China and abroad are summarized, and a series of studies of this field in the world are described as well. It is suggested that the national standard methods for the determination of 90Sr should be improved further, and a fast method for detecting 90Sr in the nuclear and radiological emergency samples should be developed.
