Description

The contents and distribution patterns of 137Cs and 239,240Pu in the sediments of the Seto Inland Sea, Japan, were determined. In most of the sediment columns, approximately uniform concentrations were found to a depth of around 20 cm, probably due to bioturbation. Total amounts of 137Cs in the sediment column are considerably lower than the global fallout inputs. It is suggested that a significant portion of 137Cs input was removed from the Seto Inland Sea to the open ocean. Large excess inventories of 239,240Pu over fallout input were observed in the investigated sediment columns. (author) 25 refs.; 3 figs.; 3 tabs
