本文利用受1.78mGy/d 和4.27mGy/dγ线连续照射三年(累积剂量分别为1.314±0.078Gy 和3.152±0.192Gy)的两组狗,在停止照射后三年期间对其生物效应恢复的动力学规律进行了观察。结果表明:受照狗在照射期间产生的生物效应或损伤是可逆的,停照后经过不同时间可以恢复,多数效应在停照后3-6个月恢复较明显,唯细胞免疫功能恢复较慢,需2-3年才能完全恢复。
In this paper, two groups of dogs that were continuously irradiated for three years (cumulative doses of 1.314 ± 0.078Gy and 3.152 ± 0.192Gy respectively) by 1.78mGy / d and 4.27mGy / dγ ray were used to recover their biological effects during the three years after the irradiation was stopped Kinetic laws were observed. The results showed that the biological effects or damages of irradiated dogs during the irradiation were reversible. After stopping the irradiation, the animals recovered at different times. The majority of the effects recovered more obviously 3-6 months after the suspension, and the recovery of cellular immunity was slower , Take 2-3 years to fully recover.
