title: [Comparison of the biological effects of tritium oxide and gamma radiation based on changes in the mass of the rat thymus gland].
abstract: RBE of tritium oxide (cumulative doses from 0.33 to 14.7 Gy), in comparison with gamma-radiation, amounted to 2-3 as estimated by the thymus mass. As determined by the rate of injury and repair, the RBE values decreased from 4 to 1.4 with dose increasing, and from 6.5 to 1.3, by the periods of half-decrease and half-recovery of the organ mass. The 2-3-fold variations in the RBE values for various parameters of the organ mass changes were registered at low doses, whereas within the range of median and high doses under study, the differences were insignificant.
