Abstract: Artificial radionuclides are the source of global nuclear pollution. With the rapid development of coastal nuclear energy utilization worldwide, and the impact of Chernobyl and Fukushima nuclear leakage accidents, the international community has paid more and more attention to marine nuclear pollution and the consequent public health problems. Artificial radionuclides enter the sea by a variety of ways, migrate and spread in the sea, and are accumulated in the marine fish with high trophic level through the food chain. Once they enter the market by fishing, they will eventually harm human health. This paper reviews the research progress on the pathways of artificial radionuclides entering the sea, their diffusion and migration modes in the sea, and their enrichment, distribution and radiation damage effects in marine fishes. Based on the analysis of the current situation of marine nuclear safety and the problem of nuclear pollution in marine fisheries, it is suggested that we should strengthen related research in the future on the mechanism of artificial radionuclides travelling up the food chain, the migration pattern of marine fish carrying artificial radionuclides, the possible effects of chronic nuclear radiation on different life stages of fish, and the establishment of a new international marine nuclear safety standard system to provide scientific reference for the global governance of marine nuclear pollution.
