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。
Objective To detect the micronuclei of peripheral blood lymphocytes of radiation workers exposed to Am (Am) in an enterprise and provide a scientific basis for occupational health protection and occupational health monitoring. Methods According to the routine culture method regulated by the national standard WS / T 187-1999, the micronuclei of lymphocytes in radiographers were detected and analyzed. Results Compared with the control group, the micronucleus rate of radioactive workers who exposed to 镅 element in 2010 was significantly different (χ2 = 20.24, P <0.01). There was significant difference in the micronucleus rate between radiation workers in each age group (χ2 = 361.27, P <0.05). There was significant difference in the micronucleus rate of radiographers in each age group (χ2 = 37.02, P <0.05). There was no significant difference in the micronucleus rate of radiographers in different occupations (χ2 = 3.89, P > 0.05). The conclusion shows that long-term, low-dose exposure to 镅 element has a certain damage effect on the human body, and the awareness of radiation workers should be strengthened to improve working conditions and ensure the health of employees.
