“…In coastal areas, absorbed dose rates of up to 4,600 mGy d −1 for macroalgae and 2,600 mGy d −1 for benthic biota (fish, molluscs, and crustaceans) were estimated from exposure to 131 I, 134 Cs, and 137 Cs (both internal and external) during the first month after the initial FDNPP release, assuming equilibrium with ambient radionuclide activities (Garnier-Laplace et al 2011). However, subsequent studies have shown that these estimates were likely an overestimate, as Cs and 131 I activities declined rapidly (Buesseler et al 2011, Kryshev et al 2012). …”

The events that followed the Tohoku earthquake and tsunami on March 11, 2011, included the loss of power and overheating at the Fukushima Daiichi nuclear power plants, which led to extensive releases of radioactive gases, volatiles, and liquids, particularly to the coastal ocean. The fate of these radionuclides depends in large part on their oceanic geochemistry, physical processes, and biological uptake. Whereas radioactivity on land can be resampled and its distribution mapped, releases to the marine environment are harder to characterize owing to variability in ocean currents and the general challenges of sampling at sea. Five years later, it is appropriate to review what happened in terms of the sources, transport, and fate of these radionuclides in the ocean. In addition to the oceanic behavior of these contaminants, this review considers the potential health effects and societal impacts.

“…Radioactivity was significantly released into the environment, and a large marine ecosystem in the Pacific Ocean along the eastern coast of Japan was contaminated by the radioactivity. After the accident, the radiation effect on the marine biota as the result of the accident was investigated in a few studies (Garnier-Laplace et al, 2011;Kryshev et al, 2012;Keum et al, 2013Keum et al, , 2014. The initial studies were mostly based on an equilibrium approach, and there have been relatively few dynamic approaches.…”

“…This allowed the refinement of early estimates that had identified the potential for ecological consequences (Garnier-Laplace et al, 2011) but, since equilibrium of the biota with maximum ambient concentrations had been assumed, this led to higher exposures than subsequently calculated (Buesseler et al, 2011;Kryshev et al, 2012;Vives i Batlle, 2011 were not to be expected (UNSCEAR, 2014). The more recent IAEA study provides an evaluation consistent with these findings (IAEA, 2015).…”

This paper focuses on how a community of researchers under the COMET (CO-ordination and iMplementation of a pan European projecT for radioecology) project has improved the capacity of marine radioecology to understand at the process level the behaviour of radionuclides in the marine environment, uptake by organisms and the resulting doses after the Fukushima Dai-ichi nuclear accident occurred in 2011. We present new radioecological understanding of the processes involved, such as the interaction of waterborne radionuclides with suspended particles and sediments or the biological uptake and turnover of radionuclides, which have been better quantified and mathematically described.We demonstrate that biokinetic models can better represent radionuclide transfer to biota in nonequilibrium situations, bringing more realism to predictions, especially when combining physical, chemical and biological interactions that occur in such an open and dynamic environment as the ocean. As a result, we are readier now than we were before the FDNPP accident in terms of having models that can be applied to dynamic situations.The paper concludes with our vision for marine radioecology as a fundamental research discipline and we present a strategy for our discipline at the European and international levels. The lessons learned 2 are presented along with their possible applicability to assess/reduce the environmental consequences of future accidents to the marine environment and guidance for future research, as well as to assure sustainability of marine radioecology in Europe and globally. This guidance necessarily reflects on why and where further research funding is needed, signalling the way for future investigations.3
