目的通过对放射工作人员血清中三碘甲状腺原氨酸(TT3)、甲状腺素(TT4)、促甲状腺激素(TSH)检查结果的分析,了解放射工作人员甲状腺功能情况,以便改进防护措施,减少电离辐射损伤,为保障放射工作人员的健康提供依据。方法选择南京市2012年共1 854名放射工作人员甲状腺功能检查结果,按性别、年龄、工龄、吸烟、饮酒和在岗状况分组后进行比较分析。结果 TT3水平女性低于男性,差异有统计学意义(P<0.01),而TSH水平女性高于男性,差异有统计学意义(P<0.05)。TT3、TT4随着工龄、饮酒和岗位状况的变化呈下降趋势,而TSH呈上升趋势,其他分组无明显变化规律。结论长期低剂量电离辐射对放射工作人员甲状腺功能有一定影响,同时生活中不良嗜好也可能对甲状腺功能产生一定的影响,应该进一步加强放射防护措施,并且改变不良的生活方式。
Objective To understand the thyroid function of radiation workers through the analysis of the results of the examination of triiodothyronine (TT3), thyroid hormone (TT4) and thyrotropin (TSH) in the serum of radiographers in order to improve protective measures and reduce ionization Radiation damage, in order to protect the health of radiation workers to provide the basis. Methods A total of 1 854 radiation workers in Nanjing from 2012 to 2012 were retrospectively analyzed. Thyroid function test results were compared and analyzed by sex, age, length of service, smoking, drinking and on-the-job status. Results The level of TT3 was lower in females than in males (P <0.01), while the level of TSH in females was significantly higher than that in males (P <0.05). TT3, TT4 with the length of service, alcohol and post status changes showed a downward trend, while TSH showed an upward trend, no significant change in other sub-groups. Conclusion Long-term low-dose ionizing radiation may have some effects on the thyroid function of radiation workers. Meanwhile, the bad habits in life may also have some effects on thyroid function. Radiation protection measures should be further strengthened and the unhealthy lifestyles should be changed.
