我们在前一项研究中曾用2.17拉德/天的剂量率长期辐照猕猴,在连续照射2个月时睾丸已极度萎缩,嗣后便处于完全绝育状态,而外周血象直至照射57个月,仍处于正常状态,与对照动物没有明显的差异,鉴于猕猴在进化阶梯上和电离辐射的敏感性方面,都与人类较为接近,所以进一步研究猕猴的绝育剂量率、生殖细胞形态学损伤以及辐射细胞遗传学效应,对制定放射性工作人员的允许剂量标准和辐射卫生防护监测指标,都是具有重要意义的。
In the previous study, we used a dose rate of 2.17 rad / day to irradiate macaques for a long time. Testicles had been severely atrophied at 2 months of continuous exposure and subsequently completely sterilized. Peripheral blood samples were irradiated for 57 months, Are still in normal condition and have no significant difference from the control animals. Since the rhesus monkeys are close to humans in terms of the evolutionary ladder and the sensitivity to ionizing radiation, the rhesus monkeys dose-rate of sterilization, morphological damage of germ cells and the number of irradiated cells Genetic effects, the development of radioactive workers allowable dose standards and radiation health monitoring indicators are of great significance.
