Abstract
22-MeV neutrons affecting the culture of human peripheral blood lymphocytes have been studied for their cytogenetic peculiarities. Linear character of the dependence of chromosome aberrations yield within the dose range of 0.2-4.0 Gy is noted. Relative biological efficiency of 22-MeV neutrons reaches the highest values at low doses (18.8-2.4). Pair fragments and dicentrics prevail in spectrum of aberrations.
摘要
已对影响人外周血淋巴细胞培养的22兆电子伏特中子的细胞遗传学特性进行了研究。在0.2 - 4.0戈瑞剂量范围内，观察到染色体畸变产额的依赖关系呈线性特征。22兆电子伏特中子的相对生物效能在低剂量（18.8 - 2.4）时达到最高值。畸变谱中以双着丝粒体和双片段为主。
