众所周知,电离辐射是一种强诱变剂。在早期的研究中不少学者发现处于G_1期的人外周淋巴细胞或CHO组织培养细胞受照后能诱发SCE频率的增加。但也有一些学者通过对~(192)Ir事故患者和核爆幸存者外周淋巴细胞等的观察,发现SCE率并不增加,故认为辐射不是一种很强的SCE诱发剂。因此关于辐射诱发SCE的问题,目前尚存有争论。为了澄清这一问题并观察性别、吸烟、
As we all know, ionizing radiation is a strong mutagen. In the early study, many scholars found that in the G_1 phase of human peripheral lymphocytes or CHO tissue culture cells exposed to SCE can induce an increase in frequency. However, some scholars also found that the rate of SCE did not increase by observing the peripheral lymphocytes of patients with ~ (192) Ir and nuclear survivors. Therefore, some researchers think that radiation is not a strong SCE inducer. So there is still controversy over the issue of radiation-induced SCE. To clarify this issue and observe gender, smoking,
