Effect of chronic irradiation of 60Co-gamma-ray at low dose rate on rhesus monkey - effect on peripheral blood and testis.
The authors have demonstrated that after a long-term chronic irradiation of 2.17 rad/day for 2 months, the testis of the experimental monkey (Macaca mulatta) is extremely atrophied with a loss of reproductive ability. But the effect on peripheral blood is not apparent even after irradiation for 57 months. It should be noted that rhesus monkeys, being as sensitive to irradiation and similar in evolutionary steps as human beings, could be used as experimental animals to further study the dose rate for aspermatogenesis, the morphological injuring effect on the reproductive system and the cytogenetic effect of irradiation, and this is highly important to working out a standard of promised dose of irradiation for X-ray workers and an index or radiation protection monitoring.
