[Separation of the effects of transmutation and radiation after incorporation of radionuclides into DNA (author's transl)].

abstract：:The rare earth radionuclides 177 Lu and 153Sm were administered as single i.p. injections in NMRI mice. Lu was deposited principally (up to 60%) in the skeleton if the quantity of stable carrier was low. Increase of stable carrier enhanced deposition in the reticulo-endothelial system. Sm was preferentially deposited ...
