镭同位素具有不同的半衰期,可以用来研究不同时空尺度的海洋学过程,在海洋学研究中得以广泛应用。镭同位素在海洋学中的应用主要包括溶解态物质输运,水体停留时间的估算,海洋地下水排放,沉积物的地球化学和放射年代学以及海洋水团分析5个方面的内容。从海洋中镭同位素的地球化学行为、测量方法及其在以上5个方面的研究综述了镭同位素海洋学研究进展,比较了海洋中镭同位素测量方法,阐释了各应用领域的示踪原理,给出各种应用的方法模式及公式,总结了镭同位素海洋学的发展变化,并指出我国镭同位素海洋学的发展前景和方向。

Having different half-lives, Radium isotopes can be used to study marine processes with different timescales, which have been widely used in oceanography research. The applications of radium in oceanography research consist mostly of five aspects: the transportation of dissolved material, the estimation of the residence time of seawater, the submarine groundwater discharge, the geochemistry and radio chronology of the sediments, the quantitative analysis of seawater mass. In this paper, the progresses of radium isotopes are reviewed from its geochemical behaviors, measuring methods and the five application aspects mentioned above. The measuring methods are compared with each other. The principles, method models and formulas of the five application aspects are illustrated. The progresses of radium isotope oceanography are overviewed. The development direction and prospects of marine radium research in our country are suggested.
