“…Levels of 90 Sr from the FDNPPs in atmospheric fallout were, at most, four orders of magnitude lower than 137 Cs measured on land owing to its low volatility , Tanaka et al 2014. Most of the 90 Sr released from the FDNPPs was directly discharged to the North Pacific, with estimates of total inventories ranging from 0.04 to 1.0 PBq .…”

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.

“…Due to its low volatility, the releases of 90 Sr to the atmosphere were several orders of magnitude lower than those of 137 Cs (Povinec et al, 2012;Steinhauser et al, 2014;Tanaka et al, 2014). Most of the 90 Sr released from the FDNPP was directly discharged to the North Pacific Ocean, with estimates of total inventories ranging from 0.04−1.0 PBq (Casacuberta et al, 2013;Povinec et al, 2012).…”

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

“…For the estimation of migration of radioactive Cs in the environment, the chemical state of fallout radioactive cesium in soils was investigated [6]. On the other hand, radioactivity of rubble, trees [7] and concrete structures [8] in the Fukushima Daiichi Nuclear Power Station were analyzed by radiochemical techniques to grasp the distribution of radioactivity on the site. Solution chemistry on strontium [9] and leaching behavior of radionuclides from UO 2 /ZrO 2 solid solutions [10] were investigated for future treatment of contaminated water and melted nuclear fuel.…”
