It has been established in the experiment on rats exposed to a joint action of plutonium-239, hexachlorobutadiene and ++tributyl phosphate, that manifestations of disturbances from radiation and chemical factors which are more expressed under a joint exposure, are characteristic of the thymus gland damage pattern. As far as lymphocytes count in the organ is concerned, the effect of the joint exposure is no more than additive.

3.2-fold increase of resorption of plutonium-239 administered as a 239Pu complex with tributyl phosphate (TBP) in hexachlorobutadiene (HCBD) was observed during the first 4 days in an experiment on 120 Wistar rats, as compared to the resorption level during the administration of 239Pu alone, greater accumulation in the organs of secondary deposition, followed by disappearance of differences, but for the kidneys, where the differences were observed until the end of the experiment. These features did not lead to an increase of absorbed radiation doses in the critical organs by the end of the study.
