Migration of radioactive products through alimentary chains (a review)

Data on the mobility of radioactive products in biocoenoses are presented and the main routes of their migration are discussed. Data on radioactive contamination of food products of vegetable, animal and marine origin are mentioned. It has been demonstrated that technological processing of raw material and culinary preparation of food products results in a considerable reduction in their contamination. Data on the amounts of radioactive nuclides taken up by the human organism in consequence of local and global fallout of radioactive products are reported.
