[Distribution of plutonium-239 in the body of dogs 7 days after the intravenous administration of a citrate complex of the metal].

In experiments with 12 dogs of both sexes it was found that 7 days after intravenous injection of the citrate (2%) complex the concentration of plutonium in the organs and tissues, which are considered noncritical, is lower than in the skeleton by one or two orders of magnitude. No substantial differences were found in plutonium levels in the endocrine glands, (0.7-4.2) X 10(-3%), different parts of the gastrointestinal tract, (0.9-1.7) X 10(-3%), different regional lymph nodes, (2.4-3.8) X 10(-3%), and in different parts of the central nervous system, (0.06-0.19) X 10(-3%) of the total amount of plutonium administered.
