Abstract: | 137Cs in the marine environment mainly originates from fallout of atmospheric nuclear weapon tests, accidental releases from nuclear facilities, and from the Chernobyl accident. After the latter accident, many studies have been carried out in Turkey. The objective of this study is to assess the spatial distribution of 137Cs in the coastal marine environment of the Aegean Sea.The concentrations of 137Cs in sediment, sea water, mussel (Mytilus galloprovincialis), and fish samples collected from the coast of the Aegean Sea at Izmir Bay and near Didim (Akbük) have been monitored for seasonal variability by the means of gamma spectroscopy: they vary between 0.10 ± 0.01 and 1.5 ± 0.3 Bq kg?1, 1.3 ± 0.1 and 4.3 ± 0.4 Bq m?3, <0.2 and 1.3 ± 0.3 Bq kg?1, and 0.20 ± 0.03 and 1.8 ± 0.3 Bq kg?1, respectively. |
