【摘要】 本文采用不同剂量的^?C₀—γ射线对小白鼠作一次性全身均匀照射,诱发骨髓细胞染色体畸变。统计各种类型的畸变,对结果进行回归分析,作出了剂量—效应曲线。在实验的辐射剂量范围内剂量—效应关系呈线性。更多还原

【Abstract】 Chromosome aberration of bone marrow was found after the whole mice wereirradiated homogeneously onee with different doses of ⁶⁰C₀—γ ray.The types ofabberrations were counted and a dose-effect curve was used to represent the resultsanalyzed by regresisve method.The results indicate that ⁶⁰C₀-γ can induce chrom-osome aberration in number and structure of mice bone marrow,the aberration ratewas higher and the effects of irradition on chromosomes depended on the doses of（60）C₀-γ with the dosage used in this paper.更多还原
