[Comparative study of hazards of energy plutonium and standard Pu-239 using non stochastic effects].

In experiment with rats it was found that the "energy" Pu is more toxic than standard 239Pu when entered endotracheally. The comparison was made by the non-stochastic effects. The toxicity in respiratory system and blood system was 1.

[Modifying effect of tributylphosphate (TBP) and hexachlorbutadien (HCLB) on non-stochastic effects of inhaled Pu-239].

It has been established in experiments on rats that under combined inhalation exposure to 239Pu along with TBP and HCLB in amounts which may cause the changes in blood and immune systems the enhancing of different non-stochastic effects on the average by two times on a basis of a unit absorbed dose in comparison with isolated nuclide inhalation.
