Popis: Summary Whole-body γ -radiation of mature Hereford bulls with a single dose of 400 r from a cobalt 60 source did not result in any apparent change in semen characteristics (sperm concentration and initial fructose level) or in sperm activity (initial motility and fructolytic activity) during a 3-wk. post-irradiation period. Evidently, those cells which were past the radiosensitive spermatogonial stage at the time of irradiation were metabolically unaffected.
