Dose-response data for X-ray induced translocations in spermatogonia of Rhesus monkeys

The yields of translocations in spermatocytes after irradiation of spermatogonia of Rhesus monkeys with doses of 100, 200 or 300 rad X-rays were low, and consistent with a humped dose-response curve with a peak at about 200 rad. Such a curve would agree well with earlier results on the marmoset and man, but the yields at any dose in the Rhesus monkey were lower.
