在~(60)Coγ-线事故后1—3年,对事故中13名受射人员(医务人员9名,肿瘤病员4名)进行了细胞遗传学研究。结果表明,尽管相隔1—3年,淋巴细胞中的染色体畸变仍不失为一个灵敏而可靠的指标。受检医务人员的大多数均可由染色体畸变察觉其放射损伤,即便剂量低至5拉德也不例外。至于肿瘤病员,畸变率更高,除双着丝粒体外,还可见到3着丝粒体、4着丝粒体等多次击中畸变。 One to three years after the Accident of the ~ (60) Coγ-line, cytogenetics studies were conducted on 13 shots (9 medical workers and 4 oncology patients) in the accident. The results show that, despite 1-3 years apart, chromosomal aberrations in lymphocytes are still a sensitive and reliable indicator. Most of the medical personnel under test are aware of their radiation damage from chromosomal aberrations, even at doses as low as 5 rad. As for cancer patients, the higher the rate of distortion, in addition to dicentric mitochondria, you can also see the 3 cenospomes, 4 mitochondrial hits multiple distortions.
