It briefly introduces the researches on radionuclide migration in the ocean, such as90 Sr、137Cs、 95Zr、110mAg、60Co and 3H. The rules of radionuclide migration in the mediums of seawater、suspended matter、sed-iment and halobios are mainly discussed.%简要介绍了锶-90(90Sr)、铯-137(137Cs)、锆-95(95Zr)、银-110m(110mAg)、钴-60(60Co)和氚(3H)等核素在海洋中迁移研究的情况,集中探讨了放射性核素在海水、悬浮物、沉积物和海洋生物等介质中的运动规律.
