AbstractThe aim of the work was to determine 241Pu activities in different components (water, plankton and fish) of the southern Baltic Sea ecosystem. Measurement of 241Pu in the samples was done indirectly by determining the increment in 241Am from the decay of the 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 highest 241Pu concentrations in fish were found in Perciformes: benthic round goby (0.863 ± 0.066 mBq/g ww) and pelagic perch (0.666 ± 0.001 mBq/g ww). Plutonium is also non-uniformly distributed in the organs and tissues of the analyzed fish; especially pelagic herring and cod as well as benthic flounder. Most of 241Pu in flounder, herring and cod is located in soft tissues, especially digestive organs (stomach, intestine, liver). The annual individual effective doses calculated on the basis of 241Pu concentrations in fish indicated that the impact of the consumption of 241Pu containing Baltic fish on the annual effective dose for a statistical inhabitant of Poland was very small. |
