title: [Characteristics of the descendants of male dogs exposed to chronic combined gamma-irradiation and in the postradiation period].
abstract: A study was made of the descendants of 12 male dogs subjected to gamma-irradiation during six years at dose-rates of 0.0034 Gy/day and 0.0017 Gy/day + additional annual exposures to gamma-radiation three times a year each of 0.42 Gy. The observations were made during 3 years after the end of irradiation. It was shown that the descendants reflected the regularities of the disorders revealed in fathers' spermatogenesis. The radiobiological effects were function of dose--rate and cumulative radiation dose. The changes were mainly noted during embryogenesis and manifested by the sterility, mortinatality and the decreased number of puppies in the postreity.
