作者调查了95名生活与工作在较高天然放射性地区由于吸入氢及其子体所致外周血淋巴细胞染色体畸变。受检者所受γ射线外照射相似于一般地水平,估算吸入氢及其子体所致α射线血液剂量为0.007～12雷姆/年。染色体畸变分析指标为间隙、染色体与染色单体断裂
The authors investigated chromosomal aberrations in peripheral blood lymphocytes from 95 living and working in higher natural radioactive areas due to inhaled hydrogen and its daughters. Subjects were exposed to γ-ray external irradiation similar to the general level, estimating the inhalation of hydrogen and its progeny due to α-ray blood dose of 0.007 to 12 m / year. Chromosome aberration analysis of indicators for the gap, chromosomes and chromatid breaks
