of the Food chain and the experimental portion of two curium studies and one neptunium study have been completed. However, the analysis of the ata from these studies is not as yet complete, but will probably be presented at the next NAEG annual meeting. As a part of an EPA” funded program, our Laboratory has recently published a literature review on "The Availability, Uptake and Translocation of Plutonium Within Biological Systems" by Mullen and Mosley (1976) This introduction serves to introduce the next four speakers who will cove their studies in detail. Drs. Bradley and Moor will cover the small indi ° vertebrates, Dr. Sutton will discuss the transport to milk, Dr. Smith wit review the grazing studies, and Mr. Barth will discuss the application and significance of the artificial rumen and simulated gastrointestinal eystems REFERENCES "Ecological Studies of Small Verte1975, Bradley, W.
