Accumulation of 210Po in selected species of Baltic fish

Results are presented here for the 210Po contents of selected species of Baltic fish. It is shown that 210Po is non-uniformly distributed within these fish, the highest levels being found in the digestive organs, particularly within the intestine. It is found that the proportional contribution by the digestive organs to the total accumulation of 210Po is correlated with the degree of repletion of the stomach and that this decreases if food is lacking. Moreover, it is observed that fish represent an important source of supply of 210Po to humans. (author)
