摘要：

The radionuclide content of 54 sediment samples collected from IS locations distributed along the Vojvodina part of the Danube was determined by means of low-level, high-resolution gamma-spectroscopy. Beside the members of the natural radioactive chains of U-238, Th-232 and the natural K-40, Cs-137 content of Chernobyl origin was also detected. The data obtained are compared with those collected during four years starting after the Chernobyl accident, and the elimination rate of (CS)-C-137 from the river ecosystem is discussed. No traces of after-Chernobyl (CS)-C-137 were found. The radioactivity of the Danube sediment is now similar to the pre-Chernobyl era. (c) 2005 Elsevier Ltd. All rights reserved.
