某工厂775名接触镅的放射工作人员外周血淋巴细胞微核检查结果分析

目的检测某企业接触镅(Am)的放射工作人员外周血淋巴细胞微核,为职业卫生防护及职业健康监护提供科学依据。方法根据国家标准WS/T 187-1999规定的常规培养法,检测并分析放射工作人员淋巴细胞微核。结果 2010年接触镅元素的放射工作人员微核率与对照组相比差异有统计学意义(χ2=20.24,P<0.01);各年龄组放射工作人员微核率差异有统计学意义(χ2=361.27,P<0.05);各工龄组放射工作人员微核率差异有统计学意义(χ2=37.02,P<0.05);不同工种放射工作人员微核率差异无统计学意义(χ2=3.89,P>0.05)。结论说明长期低剂量接触镅元素对人体有一定的损伤作用,应该加强放射工作人员的防护意识,改善工作条件,保证从业人员的健康。

Peripheral blood lymphocyte micronucleus of 755 radiation workers exposed to americium in the company

Objective To detect the peripheral blood lymphocyte micronucleus of the radiation workers exposed to americium in the company and provide scientific basis for occupational health protection and monitoring.Methods The peripheral blood lymphocyte micronucleus of the radiation workers were detected and analyzed in accordance to the method prescribed in the national standards(WS/T 187-1999).Results The difference between radiation workers exposed to americium in 2010 and the control group had statistical significance(χ2=20.24,P<0.01);the micronucleus rate between different age-group radiation workers had statistical difference(χ2=361.27,P<0.05);the micronucleus rate between male and female workers had no statistical difference(χ2=3.89,P>0.05);the micronucleus rate between different seniority-group radiation workers had statistical significance(χ2=37.02,P<0.05);the micronucleus rate between different kinds of radiation workers had no statistical significance(χ2=2.64,P>0.05).Conclusion Long exposure to americium is harmful to human body.Therefore,protective awareness should be strengthened and working conditions should be improved.
