“…The nuclear accidents at Chornobyl and Fukushima have led to the direct contamination of the marine environment as well as the terrestrial environment, which has then led to secondary sources to the marine environment through rivers, surface runoff and, where relevant, submarine groundwater discharge 75,76 . When such accidents occur, the fluxes of radionuclides through these pathways are generally highest in the years following the accident and then decrease over time as the mobile fraction of deposited radionuclides is reduced through washout and physical decay [77][78][79][80][81] . Accidents and/or previous working practices at other nuclear facilities have also resulted in contamination of the terrestrial environment that has and continues to provide inputs to the marine environment via river runoff (Box.…”

Climate change interacts with the sources and cycling of contaminants, such as radionuclides, in the environment. In this review, we discuss the implications of climate change impacts on existing and potential future sources of radionuclides associated with human activities to the marine environment. The overall effect on operational releases of radionuclides from the nuclear and non-nuclear sectors will likely be increased interference or prevention of normal operations due to weather-related events. For certain radioactive waste dumped at sea and sunken nuclear submarines, the impact of climate change and ocean acidification on the release of radionuclides and their subsequent fate in the marine environment should be considered further. Fluxes from secondary sources of radionuclides in the marine and terrestrial environment and cryosphere will change in response to climate change impacts such as sea level rise, warming and changes in precipitation patterns. In addition, climate change impacts may increase the risk of releases of radionuclides from operational and legacy wastes on land to the marine environment. Overall, our synthesis highlights that there is a need to understand and assess climate change impacts on sources of radionuclides to the marine environment to meet environmental and management challenges under future climate scenarios.
