Radioactivity data (Bq/kg) from sea bottom and lake sediment samples collected in the 1987-88, 1988-89 and 1989-90 Italian expeditions in Antarctica are presented. Vertical distribution of Cs-137 in lake sediment cores and soil pits collected in the 1989-90 Expedition are discussed, together with the resulting inventories of the radionuclide; comparisons with literature data concerning both specific activities and inventories are also reported.

Abstract
Radioactivity data (Bq/kg) from sea bottom and lake sediment samples collected in the 1987-88, 1988-89 and 1989-90 Italian expeditions in Antarctica are presented. Vertical distribution of Cs-137 in lake sediment cores and soil pits collected in the 1989-90 Expedition are discussed, together with the resulting inventories of the radionuclide; comparisons with literature data concerning both specific activities and inventories are also reported.File in questo prodotto:
