[Biochemical changes in rat tissues as affected by the combined action of external gamma-radiation and 239Pu in different doses].
Under the combined effect of external gamma-radiation (25.8 and 103.2 mC/kg) and 239Pu (18.5 and 92.5 kBq/kg body weight) the changes in the nucleic acids of rat thymus tissues depended upon the intensity of gamma- and alpha-radiation. The damage to the thymus produced by the combined effect was weaker than that of the effect of the two types of radiation delivered separately. In bone tissue, summation of the oppositely directed changes in alkaline phosphatase activity was registered after the effect of gamma-radiation and 239Pu delivered separately.
