title: 241Pu in the biggest Polish rivers.
abstract: In the paper the results of241Pu activity concentration determination in the biggest Polish rivers are presented. The analysis of more than 100 river water samples showed the Vistula and the Odra as well as three Pomeranian Rivers are important sources of241Pu in the southern Baltic Sea. There were differences in241Pu activities depending on season and sampling site and the plutonium contamination came mainly from the global atmospheric fallout as well as the Chernobyl accident, which is confirmed by plutonium activity ratios of241Pu/239+240Pu and238Pu/239+240Pu.
