Abstract: The fate of radiocesium transported by rivers to the Adriatic Sea and accumulated in sediments was investigated in the Northern Adriatic coastal area. Concentrations and inventories obtained for the areas of influence of the most important rivers (Tagliamento, Isonzo, Piave, Adige and Po) were compared. Radiocesium preferentially accumulates in the prodelta areas. In 1987137Cs maximum concentrations and inventories in these zones ranged between 200 and 300 Bq kg-1and between 12 and 64 kBq m-2, respectively. The temporal dynamics in selected zones was studied by sampling at the same site in different years. Temporal differences in the radionuclide inventories show that some areas are unstable on the time scale of one year due to sediment resuspension processes. © 1997 Elsevier Science B.V.
