| Abstract: | An experiment was conducted in fresh‐water fish (Cyprinus carpio) cultured, in small water tanks, artificially contaminated with radioactive 137Cs (3000 Bq/1) to determine the uptake of 137Cs and its physiological and histological effects in different fish organs. It was found that 137Cs was located in muscular tissues, gills, head muscles, liver and kidneys. Moderate amounts were found in spleen, eyes, gonads, intestine and urinary bladder. It seems that sorption was of much less importance than ingestion in the uptake of 137Cs. The histological examination in musculature tissue, revealed an acute hyperemia with focal hemorrages which may be due to allergic effects of 137Cs. Hyperemia and focal fatty degeneration of hepatic cells was also noted in the liver which may be due to toxic effects of 137Cs diffused hyperemia has also occurred in the brain and focal degeneration of epithelial cells of renal tubules. |
