Abstract

The ashes of the livers of fishes caught in the Pacific Ocean in 1958 were analyzed for their radio contamination by the ion exchange and precipitation methods. As a result, some radio nuclides, 59Fe, 65Zn, 115mCd and 90Sr+90Y were identified with the measurements of their halflives, absorptions and energies. The maximum concentrations of the elements determined were 59Fe of 4.0 × 10-3 μc, 65Zn of 4.0 × 10-1μc, 115mCd of 6.3 × 10-3 μc, and 90Sr+90Y of 2.5 × 10-5 μc.
