Özet

Radionuclide (Cs-137, U-238, Th-232 and K-40) concentrations were determined in a sediment trap and bottom sediment samples collected from a station at the eastern Turkish coast of the Black Sea. The specific activity of the Cs-137 radionuclide in the settling particles ranged from 0.04 +/- 0.01 to 0.10 +/- 0.02 Bq.g(-1) dry weight. The calculated flux rate of the Cs-137 was between 0.37 and 2.59 Bq.m(-2).d(-1) stopin the sampling periods of 2002 and 2003. The Cs-137 concentration in the bottom sediment profile were between 0.039 +/- 0.013-9.083 +/- 0.017 Bq.g(-1) dry weight in the same station. The vertical profile of the radionuclides suggests that they have little mobility during the 17 years after the Chernobyl accident.
