[Evaluation of the effects of biological and clinical factors on plutonium excretion in man].

The values of the natural urine excretion coefficient in 84 workers have been received. The observations were ranging from 1970 to 1984. To analyse this data the references about radiobiological, medical, anthropometrical and other factors which potentially influence osteotropic radionuclide excretion in man and animals have been studied.

[Quantitative evaluation of the effectiveness of exposure of the joints to 239Pu and tributyl phosphate by the degree of leukopenia in rats].

The efficiency of the combined effect of 239Pu and tributyl phosphate was estimated by the severity of leucopenia in Wistar rats using the regression method and comparing the value of the actual change with the expected one. It was shown that the additive effect of the two agents delivered simultaneously was only exceeded when their doses were the largest that is, approximate the acute levels. With levels ranging from subacute effective to minimum effective ones the additivity diminished.
