  • Title: [Relative biological effectiveness of tritium oxide by the criterion of death of the germ cells in mice].
    Author: Balonov MI, Kudritskaia OIu, Bruk GIa.
    Journal: Radiobiologiia; 1984; 24(1):114-7. PubMed ID: 6369381.
    Abstract:
    It was shown that low-level beta-radiation of tritium is much more effective than gamma-radiation of 137Cs with respect to reduction of the mouse testis weight. The RBE coefficient increases from 1.8 at a dose of 1 Gy to 2.2-2.3 at 0.1 Gy. On the basis of the data obtained by the authors and those reported in the literature a quality factor is proposed for tritium: QF = 2. Using THO and Na36Cl labels a mean water content of the testis cells, necessary for the estimation of a tritium-radiation dose absorbed, has been determined: gamma ct = 0.70 +/- 0.02 ml/g.
