A study was made of spermatogenesis in 15 dogs after discontinuing 3-year exposure to ..gamma..-radiation at a dose rate of 0.34 rad/day and 0.17 rad/day + 3 annual dose loads of 8 and 42 rad (cumulative doses of 375, 360 and 570 rad). Partial restoration of spermatogenesis was demonstrated. At the first stage (1 to 1.5 years) normalization was very intensive in dogs submitted to the maximum damage (cumulative dose 570 rad). Thereafter (3d to 6th years), there was slowing of recovery rate and the process of spermatogenesis became stabilized at a low level. There was less intensive recovery of dogs exposed to cumulative doses of 375 and 360 rad.
