Induction of translocations in mouse spermatogonia after fractionated exposure to 60Co gamma-rays.
Male mice of the Q strain were exposed to 60Co gamma-rays at 2 Gy and 2 X 2 Gy separated by increasing time intervals (from 0 min to 4 min). The chromosome translocations induced in spermatogonia were scored at diakinesis-metaphase I. A significant decrease of the translocation frequency at time intervals higher than 2 min was observed, confirming results obtained with plant materials.
