Absorption of U, Np, Am and Cm was increased by factors of 3.4, 7.1, 2.7 and 1.7, respectively, when nitrate solutions of these actinides were gavaged to adult rats fed an iron-deficient diet. Retention increased proportionately in liver, kidney and carcass. The concentration of the actinides excreted also increased substantially (over that of controls) in the urine of iron-deficient rats gavaged with /sup 233/U and /sup 237/Np, but not in those with /sup 241/Am or /sup 244/Cm. Weanling rats on an iron-deficient diet, gavaged with ferric nitrate immediately before administration of /sup 238/Pu nitrate, retained between 4% and 12% of the /sup 238/Pu retained by litter mates that were not treated intragastrically with iron.
