20条健康猕猴随机分成急性一次(223mGy/min)、分次累积(223mGy/min、每周照射一次,0.25Gy/次)、低剂量率慢性连续(每周照射5天,50mGy/day)照射及对照四个组。在0～2Gy累积剂量范围内,对猕猴造血、免疫及细胞遗传学方面的某些生物效应进行了比较研究。并在停照后一年中对上述指标的恢复过程作了动态观察。结果表明,在不同照射条件下辐射损伤的程度和特性不一,由辐射所诱发的体细胞效应大多数是可以恢复的。
Twenty healthy cynomolgus monkeys were randomly divided into acute (223mGy / min), cumulative (223mGy / min, once weekly, 0.25Gy / time) and chronic low dose (50dGy / day weekly irradiation for 5 days) And control four groups. Some biological effects on hematopoiesis, immunity and cytogenetics in macaques were compared over a cumulative dose range of 0-2 Gy. And made a dynamic observation on the recovery of the above indicators in the year after the suspension of the license. The results showed that the degree and characteristics of radiation damage under different irradiation conditions were different, and most of the somatic effects induced by radiation were recovered.
