Radionuclide levels in fish off Fukushima are highly variable but remain elevated, indicating a continuing source of radiation. The triple disaster of the 11 March 2011 earthquake, tsunami, and subsequent radiation releases at Fukushima Dai-ichi were, and continue to be, unprecedented events for the ocean and for society. More than 80% of the radioactivity from Fukushima was either blown offshore or directly discharged into the ocean from waters used to cool the nuclear power plants (1… Expand
Effects of the nuclear disaster on marine products in Fukushima.
Long-term and careful monitoring of marine products in the waters off Fukushima Prefecture, especially around the FDNPP, is necessary to restart the coastal fishery reliably and to prevent harmful rumors in the future. Expand
Fukushima Daiichi-Derived Radionuclides in the Ocean: Transport, Fate, and Impacts.
Five years after the Tohoku earthquake and tsunami, it is appropriate to review what happened in terms of the sources, transport, and fate of these radionuclides in the ocean, and the potential health effects and societal impacts are considered. Expand
Impacts of the Fukushima Nuclear Accident on Fish and Fishing Grounds
This book presents the results from the Japanese Fisheries Research Agency s 3-year intensive monitoring of radionuclides in a variety of fish, plankton, benthos, and their living environments afterExpand
The aftermath of the Fukushima nuclear accident: Measures to contain groundwater contamination.
This paper presents an overview of work undertaken to contain the spread of radionuclides, and to mitigate releases to the ocean via hydrological pathways at the Fukushima Daiichi Nuclear Plant. Expand
Monitoring long-term ecological impacts from release of Fukushima radiation water into ocean
Abstract After 10 years of the Fukushima Nuclear Accident, Japan decided to release the nuclear wastewater into the Pacific Ocean on 13 April 2021. It is apparent that Japan has chosen the mostExpand
Analysis of 137Cs concentration in marine sediments near Fukushima nuclear power plants
When a severe accident occurs at a nuclear power plant, lots of radionuclides are released and most of them finally moves into the sea. The seawater generally flows into the open seas and, thus, theExpand
Slower Decrease in Radioactive Concentrations in Some Fish Species After the Fukushima Daiichi Nuclear Power Plant Disaster
Large quantities of radioactive material were released into the ocean as a result of the Fukushima Daiichi Nuclear Power Plant disaster. Because of the movement of the highly radioactive water mass,Expand
Bluefin tuna accumulated Cs and Cs released from the Fukushima nuclear power plant in Japan and transported these isotopes to the eastern Pacific. Radiation doses to the tuna and to human seafoodExpand
Environmental and Economic Recovery Post-Fukushima Daiichi Nuclear Disaster: Isotope Characteristics and the Recovery of a Crippled Fisheries Industry
The 2011 Tohoku earthquake and subsequent tsunami had a catastrophic effect on the aquaculture industry of the North-East Japanese coast. Ten years on, this paper examines the environmental andExpand
Assessing Fukushima-Derived Radiocesium in Migratory Pacific Predators.
Nondetection of 134Cs and low levels of 137Cs in diverse marine megafauna far from Fukushima confirms negligible increases in radiocesium, with levels comparable to those prior to the release from Fukushima. Expand


Impacts of the Fukushima nuclear power plants on marine radioactivity.
Data show peak ocean discharges in early April, one month after the earthquake and a factor of 1000 decrease in the month following, but concentrations through the end of July remain higher than expected implying continued releases from the reactors or other contaminated sources, such as groundwater or coastal sediments. Expand
Fukushima-derived radionuclides in the ocean and biota off Japan
Risks to public health and marine biota are addressed by showing that though Cs isotopes are elevated 10–1,000× over prior levels in waters off Japan, radiation risks are below those generally considered harmful to marine animals and human consumers, and even below those from naturally occurring radionuclides. Expand
Tracking the Fukushima Radionuclides
Detailed maps are beginning to provide a picture of the contamination patterns, but as radionuclides migrate and diffuse through the environment, continual monitoring is required to guide remediation and ensure human safety. Expand
Pacific bluefin tuna transport Fukushima-derived radionuclides from Japan to California
It is reported unequivocal evidence that Pacific bluefin tuna, Thunnus orientalis, transported Fukushima-derived radionuclides across the entire North Pacific Ocean, and tools to trace migration origin (using the presence of 134Cs) and potentially migration timing (using 134Cs:137Cs ratios) in highly migratory marine species in the Pacific Ocean.

Bioaccumulation of Radiocesium by Fish: the Influence of Physicochemical Factors and Trophic Structure
Although many measurements have been made on radiocesium levels in water and aquatic biota, no agreement has been reached regarding the factors affecting bioaccumulation of these radionuclides. WithExpand
The elimination of radiocaesium from fish
The generality of the new model for the elimination of radiocaesium from fish provides aquatic ecologists with the means to simplify greatly and improve existing methods for estimating ration for fish through the use of 137 Cs based bioenergetics models. Expand
Trophic Position and Metabolic Rate Predict the Long-Term Decay Process of Radioactive Cesium in Fish: A Meta-Analysis
Ecological and biological traits are important to predict the long-term decay process of 137Cs activity concentration in fish and the metabolic rate of the fish species and environmental water temperature could predict ecological half-lives and decay rates for fish species. Expand

References and Notes
our experimentation could eventually be used to discredit our findings, should they happen not to agree with the original observations. It seems important that all experiments in the rapidlyExpand
