引言在我们以前报告的第一篇材料内已经指出,在广岛和长崎受原子弹爆炸存活下来的人中,辐射引起的外周血淋巴细胞染色体畸变一直持续很多年;畸变细胞的频率与每个个体所接受的照射剂量成正比。结果表明,对辐射诱发的畸变细胞的计数乃是评价人们晚期体细胞辐射效应的一个有用的指标. 本文详细地叙述染色体分析的结果。样品来自广岛和长崎受原子弹爆炸而存活下来的人的外周血培养淋巴细胞,进一步得到了有关晚期体细胞辐射效应的详细资料,阐明了染色体畸变与剂量、受照射时机体的年龄、原子弹辐射成份等因素的关系。
INTRODUCTION As noted in the first report we previously reported, chromosomal aberrations in peripheral blood lymphocytes caused by radiation have persisted for many years in those who survived the atomic bombing in Hiroshima and Nagasaki; the frequency of aberrant cells correlated with each individual Received radiation dose is proportional. The results show that counting radiation-induced aberrant cells is a useful indicator for evaluating the effect of late somatic radiotherapy in humans.This article describes in detail the results of chromosome analysis. Samples from peripheral blood from surviving atomic bomb in Hiroshima and Nagasaki were used to culture lymphocytes. Further information on the effects of late somatic cell radiation was obtained. Chromosome aberration and dose were also elucidated. The age of the body, the atomic bomb radiation Composition and other factors.
