By the size segregation of sediment, the contents of 239Pu, 137Cs and 60Co were found to reach to the highest value in the fraction below 37 μm in diameter. The concentrations of these radionuclides for each size fraction were directly proportional to the amount of glycerol adsorbed on the sediment particles. Based on these facts, the normalization of the concentration of these artificial radionuclides by the amount of adsorbed glycerol was attempted. For the fraction below 0.5 mm in diameter of various sediments collected at around Urazoko Bay during 1975-1977. It was confirmed that the contents of 239Pu and 137Cs per unit amount of adsorbed glycerol were nearly constant, respectively. Furthermore, the pollution characteristics of 60Co in the sediments, such as the distribution and the accumulation, was clearly estimated by using such normalization., 金沢大学環日本海域環境研究センター}, pages = {264--275}, title = {Distribution and Behavior of ^<239>Pu, ^<137>Cs and ^<60>Co in the Sediment at Urazoko Bay}, volume = {20}, year = {1979} }
