目的探讨南京市放射工作人员血清中甲状腺激素含量的变化,为南京市的放射防护管理工作提供科学依据。方法化学发光免疫测定法,以南京市2015年从事放射工作的2019名人员以及同期从事非放射工作的298名人员为研究对象,检测其血清中游离T3、游离T4以及促甲状腺激素含量并进行分析。结果放射组的FT3和FT4含量均高于对照组,而TSH水平低于对照组,差异有统计学意义(P<0.05)。放射作业人员中,男性的FT3和FT4含量显著高于女性,而TSH含量显著低于女性(P<0.05)。结论放射工作人员因长期低剂量接触电离辐射,甲状腺功能受到了一定的损伤,在工作中应加强对甲状腺部位的防护。
Objective To investigate the changes of serum thyroid hormone levels in radiation workers in Nanjing and provide a scientific basis for the radiation protection management in Nanjing. Methods Chemiluminescence immunoassay was used to analyze the contents of free T3, free T4 and thyrotropin in 2019 people engaged in radiology in Nanjing in 2015 and 298 non-radiation workers in the same period. . Results The levels of FT3 and FT4 in the radiotherapy group were significantly higher than those in the control group, while the levels of TSH in the radiotherapy group were lower than those in the control group (P <0.05). Radiation workers, male FT3 and FT4 content was significantly higher than women, while the TSH content was significantly lower than the female (P <0.05). Conclusion Due to long-term and low-dose ionizing radiation exposure, thyroid function has been impaired by radiation workers. Thyroid gland protection should be strengthened during the work.
