Description
This paper reports the results obtained in the analysis of Cs-137 and Pu-239+240 in marine sediments as well as mean deposition historic of these radionuclides in the marine environment. Cs-137 and Pu-239+240 measurements were performed in marine sediments in order to estimate the deposition of these radionuclides, at 1976 to 1986, and to compare these measured values with those expected from global fallout. Samples were collected at the water-sediment boundary at several characteristic depths, from 15 to 180 m by the Oceanographic Institute (Sao Paulo University)
