This report includes information pertaining to metabolic studies of neptunium and protactinium in the adult baboon. Recent investigations have provided additional data on the uptake, distribution, retention and excretion of Np-237, Np-239 and Pa-233 in baboons following single intravenous and gavage administrations. Data is also presented on the gastrointestinal absorption of isotopes of uranium, neptunium and plutonium in individual baboons after receiving multiple gavage administrations at selected time intervals and nutritional states. The gastrointestinal (GI) absorption (f/sub 1/ values) and retention factors have been calculated for each of these nuclides. We have begun metabolic studies on the adult tamarin (Saquinis labiatus). Data are presented in this report on the preliminary results of the metabolism of Np-239 bicarbonate intravenously injected into three females and one male tamarin. These data are discussed in comparison with similar results obtained with our baboons and with other species. 28 refs., 20 figs., 14 tabs.
