Coral skeletons are natural historical records of radionuclide activity in surface seawater, and human nuclear activities such as atmospheric nuclear tests, nuclear accidents, and nuclear fuel reprocessing plants have released large amounts of radioactive materials into the marine environment since the 1940s. The study of artificial radionuclides in reef-building coral skeletons is not only important for better understanding of radionuclide levels, distribution characteristics, regulatory mechanisms, and effects of ionizing radiation in coral reef areas, but also a guide for studying the effects of human nuclear activities and the transport mechanisms of radionuclides from source areas to specific areas.
