Abstract: | This study deals with 137Cs dispersion and behaviour in the Aegean and Ionian Sea based on work done during the period 1984-1994, as a brief general review. Sea water, sediment and marine biota were analysed and measured by gamma spectrometry and the activity concentrations of 137Cs were evaluated with consideration to the sources of pollution. According to 137Cs levels the period is distinguished into three sub-periods, the pre-Chernobyl, the early Chernobyl influence and the late Chernobyl influence period. During the early period of the Chernobyl accident the 137Cs levels in the Greek marine environment increased roughly up to an order of magnitude if compared with the pre-accident ones. Since 1988, the late impact of the accident is focused mainly in the North Aegean Sea, at the Dardanelles mouth, due to the Black Sea outflow. |
