| Popis: | During the last ten years, the Italian Universities of Parma and Urbino collaborated on a special radioecological program having the aim to study the levels and the distribution of long-lived radionuclides in different marine and terrestrial matrixes. This paper summarizes the results concerning the concentrations of 239+240Pu and 238Pu, 241Am and 137Cs in sediments collected in the Ligurian and South Tyrrhenian Seas (Rapallo Harbour, Vado Ligure Canyon, Eolie Islands). Superficial sediments and sediment cores were collected. For cores the vertical distribution was calculated and the sedimentation rate obtained. 137Cs was determined directly by gamma-spectrometry, while 239+240Pu, 238Pu and 241Am were separated by extraction chromatography, electroplating and determined by alpha-spectrometry. |
