The assessment of the radiation dose to developing fish embryos due to the accumulation of radioactivity by the egg.

摘要: A dosimetry model has been developed which can be used to estimate the radiation dose received by developing embryos of plaice, Pleuro-nectes platessa, in contaminated environments. The concentration factors for nuclides ${}^{144}{\rm Ce}\text{-}{}^{144}{\rm Pr}$,137 Cs, ${}^{106}{\rm Ru}\text{-}{}^{106}{\rm Rh}$, ${}^{90}{\rm Sr}\text{-}{}^{90}{\rm Y}$, and ${}^{95}{\rm Zr}\text{-}{}^{95}{\rm Nb}$ have determined experimentally plaice eggs, data together with make estimates spawning ground northeast Irish Sea. It is found that rate from fission nuclide contamination less than due naturally occurring radionuclide potassium.
