In the recent decades, radiogeochemical methods have been increasingly used for the exploration of seas and oceans. The importance of such research can be confirmed by the creation of a large-scale international GEOTRACES program in 2010 with the purpose of identifying the processes and quantifying the fluxes that control the distribution of key micronutrients and their isotopes in the ocean, as well as their sensitivity to changing environmental conditions.
From the viewpoint of identification methods, the undoubted advantage of radioactive elements over non-radioactive elements is their disintegration, which causes the emission of elementary particles, gamma-quantums and nuclear fragments, which allows to trace many processes and phenomena as efficiently as possible without the use of labor-intensive and expensive methods. The researchers established a relationship between the gamma field and the manifestations of tectonic movements in the sedimentation process, the features of the lithological differentiation of sedimentary material and the structure. In addition, radionuclides have become a key link in the study of the interaction of coastal and ocean waters.
Radioactive tracers have become an indispensable and sometimes the only tool for research of sub-aquatic groundwater discharge. In addition to fundamental issues of the shelf structure, the properties of radionuclides have been used for the research and exploration of oil, gas and ore deposits. Thus, it is critical to continue the development and application of radiogeochemical methods in the study of the Far Eastern and Arctic Seas.
