Abstract: | An extensive programme of experiments on transfer of radionuclides to aquatic species was conducted in the former USSR starting
from the early 1950s. Only a few of these studies were made available in the English language literature or taken into account
in international reviews of radionuclide behaviour in marine ecosystems. Therefore, an overview of original information on
radionuclide transfer to marine biota species available from Russian language literature sources is presented here. The concentration
ratio (CR) values for many radionuclides and for marine species such as: 239Pu, 106Ru and 95Zr (crustacean), 54Mn, 90Sr, 95Nb, 106Ru, 137Cs 239Pu, 241Am and natural U (molluscs), and 54Mn, 90Sr, 137Cs and 144Ce (fish) are in good agreement with those previously published, whilst for some of them, in particular, for 32P and 110Ag (crustaceans), 35S (molluscs), 32P, 35S, 95Nb, and 106Ru (macroalgae) and 60Co and 239,240Pu (fish) the data presented here suggest that changes in the default CR reference values presented in recent marine reviews
may be required. The data presented here are intended to supplement substantially the CR values being collated within the
handbook on Wildlife Transfer Coefficients, coordinated under the IAEA EMRAS II programme. |
