摘要
目的:通过对鞍钢长期接触小剂量(0至100mSv)电离辐射的人员进行外周血淋巴细胞微核率的检测和分析,为加强这类人员的健康防护措施提供依据。方法:利用微量全血培养法检测200名长期接触小剂量电离辐射人员和486名非接触电离辐射人员的外周血淋巴细胞微核率并进行统计学分析。结果:长期接触小剂量电离辐射人员的外周血淋巴细胞微核率为0.715‰,是非接触电离辐射人员外周血淋巴细胞微核率(0.220‰)的3.25倍,差异具有统计学意义(P<0.01)。结论:长期接触小剂量电离辐射人员的外周血淋巴细胞微核率显著增加,致染色体发生畸变可能性增大。应加强对长期接触小剂量电离辐射人员的健康防护。
Objective： To perform cytogenetic analysis on low dose radiation （0 - 100 mSv） workers of Anshan Steel with long term exposure to low doses ionizing radiation, and provide evidence for strengthening the health surveillance of these radiation workers. Method： Method of micro amount of full blood was adopted to detect micronucleus rate of peripheral blood lymphocytes of 200 long term exposure to low dose radiation workers and 486 non - radiation workers, and statistical analysis was performed. Resuhs： Micronucleus rate of long term exposure to low dose radiation workers were 0. 715%, whieh is 3.25 times of the non - radiation workers（0.220%.）, The test results between two groups had significantly difference （ P 〈 0.01 ）. Conclusions： It was found that micronucleus rate in the peripheral blood lymphocytes of radiation workers would raised afte long - dose exposure to radiation, result in raising chance of chromosome distortion, so we should enhance radiation protection for these staffs.
