Abstract
Groups of animals (Wistar rats) were fed with rations doped with uranyl nit rate at concentrations ranging from 0.5 to 100 ppm. The uranium content in the ashes of the organs was measured by the neutron-fission track counting technique. The most striking result is that the transfer coefficients, as a function of the uranium concentration, exhibit a concave shape with a mini mum around 20ppm-U for all organs. Explanations to interpret this finding a re tentatively given. (C) 2001 Elsevier Science Ltd. All rights reserved.
