  • Title: [Relative biological effectiveness of tritium oxide based on nucleic acid metabolic indices].
    Author: Shorokhova VB, Mushkacheva GS.
    Journal: Radiobiologiia; 1985; 25(5):622-5. PubMed ID: 4070568.
    Abstract:
    Relative biological effectiveness (RBE) of tritium oxide, as compared to gamma-rays (137Cs), with regard to LD50/30 is 2,32 +/- 0,69 for rats. The RBE coefficients for tritium oxide are obtained with regard to some indices of nucleic acid metabolism in the thymus and spleen during the dose formation (0-14 days). The RBE of tritium oxide increases with a decrease in radiation dose as determined according to the concentration and content of DNA per organ and activity of thymus DNAases.
