Transport across the gastrointestinal tract of adult rats was measured for the soluble nitrate and/or insoluble oxide compounds of 228Th, 232U, 233U, 237Np, 237Pu, 238Pu, 239Pu, 241Am, 244Cm, 252Cf and 253Es. Absorption of Pu and Am nitrates was compared in adult rats, guinea pigs and dogs; there was little variation among species. Much greater variation exited between the absorption of different elements in the rat. Other factors observed to influence absorption were particle size, compound form and mass of compound administered.
