The accumulation of ⁶⁰Co, ⁵⁹Fe, ⁵⁴Mn and ⁶⁵Zn by common mussel <i>Mytilus edulis</i> and purplish bifurcate mussel <i>Septifer virgatus</i> from seawater was investigated. High accumulation of ⁵⁹Fe in Mytilus and ⁵⁴Mn in <i>Septifer</i> was observed in the uptake experiments. Differences in biological half-lives between the two species was observed for ⁵⁴Mn and ⁵⁹Fe. The organ-specific concen-tration of radionuclides observed in the mussels was high accumulation of ⁶⁰Co in kidney andviscera, ⁵⁹Fe in kidney and viscera, ⁶⁵Zn in kidney but was not observed for ⁵⁴Mn although the accumulation of ⁵⁴Mn in mantle was different between the species. Autoradiography was applied to examine the details of the distribution of ⁵⁹Fe in the soft parts of the mussels.
