| Popis: | The 239+240Pu content of the marine sediments and seawater of the costal sea of Korea was measured. In marine sediments the 239+240Pu concentrations were in the range of 0.11-1.91 Bq/kg dry weight and in the coastal sea of Korea the ratio of 239+240Pu/137Cs was 0.27. The correlations between 239+240Pu and 137Cs concentrations and the content of organic matter (C, O, H, N, S) as well as the grain size of marine sediment were investigated by regression analysis. The distribution coefficient of 239+240Pu was 1.22. 105. The 239+240Pu concentration in seawater increased with seawater depth. However, the 137Cs concentration in seawater did not change considerably with depth. |
