" The s o i l - t o - p l a n t transfer is one important parameter in the food pathway, because i t serves as a prime mechanism for entry of actinide elements into foods. Much of man's l i f e - t i m e exposure w i l l be dependent on the assimi­ lation of actinides by plants and on the eventual ingestion of vegetable foods by humans.

Compared with present-day levels of Pu entering t e r r e s t r i a l , freshwa­ ter, and marine ecosystems from global f a l l o u t , only small additional quantities of actinide elements w i l l be released from fuel cycles to the environment. Based on current fuel cycle concepts, operations involving fuel reprocessing and fabrication w i l l be the principal contributors of actinide elements to the environment. 4 mCi of man-made actinides would be released routinely for each 1000-MW(e) year of operation (2j.
