辐射诱发人体淋巴细胞染色体畸变,作为早期诊断辐射损伤的一项指标,已被人们所证实。离体人血在一定剂量的γ射线照射下,通过对淋巴细胞染色体畸变率的分析,探讨辐射剂量和畸变率的关系,为今后利用这一指标进行事故剂量分析提供依据;同时,为建立本实验室条件下的染色体畸变量与照射量之间的“刻度曲线”,用来估计受事故照射人员的吸收剂量。我们于1982年7月～12月对离体人血用~(60)CO—γ线进行了8个不同剂量组的照射,现将实验方法及
Radiation induced chromosome aberrations in human lymphocytes, as an early indicator of radiation damage, has been confirmed. In vitro human blood in a certain dose of γ-ray irradiation, through lymphocyte chromosome aberration rate analysis of radiation dose and the relationship between the rate of distortion for the future use of this indicator accidental dose analysis to provide the basis for the same time, the establishment of this The “scale curve” between the amount of chromosomal aberrations and the amount of exposure under laboratory conditions is used to estimate the absorbed dose of persons exposed to the accident. In July-December 1982, we administered 8 different doses of ~ (60) CO-γ to irradiated human blood, and the experimental methods and
