The concentrations of 241Pu in the southern Baltic Sea
University of Gdańsk, Faculty of Chemistry, Sobieskiego 18, Gdańsk, POLAND
The aim of the work was 241Pu activities determination in different components (water, plankton and fish) of the southern Baltic Sea ecosystem. The determination of 241Pu in the samples was done indirectly by activity measuring the increment in 241Am from the decay of β-emitting 241Pu in samples collected 10-15 years after the Chernobyl accident. Enhanced levels of 241Pu were observed in all analyzed Baltic samples. The plutonium is also non-uniformly distributed between the organs and tissues of the analyzed fish; especially pelagic herring and cod as well as benthic flounder. The annual individual effective doses calculated on the basis of 241Pu concentrations in fish indicated that the impact of the consumption of 241Pu with Baltic fish on the annual effective dose for a statistical inhabitant of Poland was very small.
Key words: plutonium / 241Pu / seawater / plankton / fish / Baltic Sea
