The ability of 82 irradiated and sham-treated female beagles to whelp and wean pups was tested over a major portion of their reproductive life span. The dogs were exposed to 290 or 300 R of x rays (250 kVp) either as young pups, prior to puberty, or at puberty. Although all of the irradiated dogs were fertile and produced approximately the same number of litters as controls, litters of the pup irradiated and prepubertal irradiated dams surviving throughout the study were smaller than those of controls by 17 and 9 percent, respectively. Pup survival was also reduced relative to controls; the number of pups weaned was 38 percent lower in the pup irradiated group and 18 percent lower in the prepubertal irradiated group, as compared with controls. The overall reproductive ability of dogs irradiated at puberty was similar to that of sham-treated controls.
