摘要

本文介绍了利用吸附法解决海洋放射化学问题的一般方法，包括取样、预浓缩和放射化学制备以及测量放射性核素活度的方法。讨论了在采样和样品浓度的不同阶段可能出现的方法学误差。应用最广泛的有人造(90Sr、134Cs、137Cs、239Pu、240Pu)、天然(210Pb、210Po;镭四重奏:223Ra, 224Ra, 226Ra, 228Ra;钍同位素，主要是234)和宇宙(7Be, 32P, 33P)放射性示踪剂。由于铀在海水中的浓度通常是根据已知的铀浓度与海水盐度的关系来计算的，因此没有讨论从海水中吸收铀的问题。参考书目包括200篇参考文献。

Sorption methods in marine radiochemistry

The review presents the general methodology of using sorption methods to solve problems of marine radiochemistry, including sampling, preconcentration and radiochemical preparation and methods for measuring the activity of radionuclides. The possible methodological errors at various stages of sampling and sample concentration are discussed. The most widely used artificial (90Sr, 134Cs, 137Cs, 239Pu, 240Pu), natural (210Pb, 210Po; radium quartet: 223Ra, 224Ra, 226Ra, 228Ra; thorium isotopes, mainly 234Th) and cosmogenic (7Be, 32P, 33P) radiotracers are considered. The sorption of uranium from seawater is not addressed, since its concentration in seawater is usually calculated from the known dependence of uranium concentration on seawater salinity. The bibliography includes 200 references.
