“…This is in agreement with the findings of a number of previous authors who have reported higher Cs concentrations in piscivorous, or predatory, fish compared to fish feeding on benthos, invertebrates and primary producers (e.g. Kryshev 1995, Kryshev et al, 1993Rowan et al, 1998;Rowan and Rasmussen, 1994;Saxén and Ilus, 2008;Smith et al, 2000). We should acknowledge that the data from some of these papers were included within our analyses, although they comprise a relatively small proportion of the total data available to us via the database described by Yankovich et al (in-press).…”

AbstractThe application of the concentration ratio (CR) to predict radionuclide activity concentrations in wildlife from those in soil or water has become the widely accepted approach for environmental assessments. Recently both the ICRP and IAEA have produced compilations of CR values for application in environmental assessment. However, the CR approach has many limitations most notably that transfer of most radionuclides is largely determined by site-specific factors (e.g. water or soil chemistry). Furthermore, there are few, if any, values for many radionuclide-organism combinations. In this paper we propose an alternative approach and, as an example, demonstrate and test this for caesium and freshwater fish. Using a Residual Maximum Likelihood (REML) mixed-model regression we analysed a dataset comprising 597 entries for 53 freshwater fish species from 67 sites. The REML analysis generated a mean value for each species on a common scale after REML adjustment taking account of the effect of the inter-site variation. Using an independent dataset, we subsequently test the hypothesis that the REML model outputs can be used to predict radionuclide, in this case radiocaesium, activity concentrations in unknown species from the results of a species which has been sampled at a specific site. The outputs of the REML analysis accurately predicted 137 Cs activity concentrations in different species of fish from 27 Finnish lakes; these data had not been used in our initial analyses. We recommend that this alternative approach be further investigated for other radionuclides and ecosystems.

“…The small deviations in these CF estimates are expected given the assumptions made. It should be noted that nonpredatory fish, like carp, are expected to have lower CFs for radiocaesium than predatory fish (Kryshev, 1995). Nevertheless, these CFs correspond with other reported CF values for 134 Cs and 137 Cs, which fall in the range 3 Â 10 1 e3 Â 10 3 (IAEA, 1994).…”

“…These higher sustained Cs activities are likely due to the close proximity of the fish to both the leaking FDNPP reactors and highly contaminated sediment in the harbor area. By comparison, after the CNPP accident, 137 Cs concentrations in the range 30,000-180,000 Bq kg −1 ww were reported for freshwater fish near the CNPP (e.g., Kryshev 1995).…”

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.
