Intensification of the excretory flow of plutonium-239 from the body in the late stage of its metabolism

The paper deals with the effect of iron preparations on the excretion of plutonium 239 from a body at a later stage of the radionuclide metabolism. The experimental results show that oral administration of the iron preparation at a later stage of 239Pu metabolism enhances the radionuclide excretion both in urine and in faeces. On the basis of the results obtained the coefficients are calculated for 239Pu excretion in urine and faeces and for its content in the organs of deposition. This may be used for increasing the sensitivity of indirect dosimetry of plutonium-239 within the body.
