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 (Sr-90, Cs-134, Cs-137, Pu-239, Pu-240), natural ((210)pb, Po-210; radium quartet: Ra-223, Ra-224, Ra-226, Ra-228; thorium isotopes, mainly Th-234) and cosmogenic (Be-7, P-32, P-33) 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.
