1.78 mGy/d和4.27 mGy/dγ线连续三年照射狗的结果表明,睾丸的剂量率效应要比累积剂量的效应更明显:1.78 mGy/d照射三年、累积剂量达1.314 Gy对狗的睾丸未产生影响;4.27 mGy/d照射6个月、累积剂量仅0.472 Gy时对狗的睾丸即产生了明显的效应。停照后6个月睾丸的损伤开始恢复,精子形态恢复较快,精子数量的恢复过程具有长期性和波动性。
The results of dogs irradiated at 1.78 mGy / d and 4.27 mGy / d for three consecutive years showed that the testicular dose-rate effect was more pronounced than the cumulative dose effect: 1.78 mGy / d for three years and a cumulative dose of 1.314 Gy for the testis No effect was observed. When the dose was 4.27 mGy / d for 6 months, the cumulative test dose of 0.472 Gy had a significant effect on the dog’s testis. Six months after the stop of the testis, the injury of the testicle began to recover, the recovery of the sperm morphology was rapid and the process of sperm count recovery was long-term and volatile.
