Abstrakt: Accumulation of dietary 241 Am in freshwater omnivorous fish (Carassius gibelio) was studied aiming to estimate the distribution and retention of 241 Am in the fish body. Amphipods labeled with 241 Am served as a food item. From 0.4 to 0.6% of ingested 241 Am was retained in the fish body after short courses of feeding and depuration, the trophic transfer factor of 241 Am for whole organism level was about 2∙10 -4 .
