摘要
目的对长期接触小剂量电离辐射的放射工作人员进行细胞遗传学分析,为加强对放射工作人员的健康监护提供依据。方法用微量全血培养法检测417名放射工作人员和135名非放射工作人员外周血淋巴细胞的微核率并进行统计学分析。结果观察组与对照组的微核率和微核细胞率分别为1.14‰和1.02‰及0.39‰和0.37‰。2组检测结果比较,差异有统计学意义,(P<0.01)。结论小剂量电离辐射对放射工作人员的细胞遗传学效应有一定的影响,应加强对放射工作人员的辐射防护工作。
[ Objective] To perform cytogenetic analysis on radiation workers with long-term exposure to small doses ionizing radiation, and provide evidence for strengthening the health surveillance of radiation workers. [ Methods ] Method of micro amount of full blood was adopted to detect micronucleus rate of peripheral blood lymphocytes of 417 radiation workers and 135 non-radiation workers, and statistical analysis was performed. [ Results ] Micronucleus rate and micro-nucleated cells rate of observation group and control group were 1. 14‰ and 1. 02‰ 0.39‰ and 0. 37‰. The differences of test results between 2 groups were significant （P〈0.01）. [Conclusion] Small doses of ionizing radiation have some cytogenetic effect on radiation workers; therefore, the strengthening of radiation protection to the workers is necessary.
