Reviews on ~(90)Sr measurement methods and applications in oceanographical research in environment
- 海洋环境－已发表论文 
本文综述了环境中90Sr的来源、含量水平和在陆地环境介质中的转移.重点介绍了环境中90Sr的分离测定方法,包括样品的预处理、化学分离及计数测量方法.最后介绍了与90Sr相关的海洋学研究进展,通过测量海洋环境中的90Sr可以进行水体涡动扩散、沉积物沉积速率、生物对90Sr的富集、生物和沉积物对90Sr的吸附,以及核设施运行或核事故放射性排放研究.This paper summarizes the source and contents of 90Sr in environment and its transfer in medium of land. The measurements methods of 90Sr have been introduced, including sample preparation, radiochemical separation and counting method. At last the applications of 90Sr in oceanographical research are outlined. The eddy diffusion, sedimentary rate, concentration of organism, adsorption of organism and sediment can be studied and radioactivity released from nuclide facility operation and nuclide accident can be monitored with measured content of 90Sr in marine environment.
