摘　　要：目的了解茂名地区长期职业接触低剂量电离辐射对放射作业人员甲状腺功能的影响。方法对2018年1-12月在茂名市职业病防治院进行职业健康检查的1 672名放射作业人员进行调查,用免疫化学发光法测定血清中游离三碘甲状腺原氨酸(FT3)、游离甲状腺素(FT4)和促甲状腺素(TSH)的水平,并以非接触电离辐射的942名健康检查者为对照组,进行统计分析。结果放射作业人员平均FT3和FT4水高于对照组(t=19.317、4.251,均P<0.01),TSH水平低于对照组(t=6.327,P<0.01)。放射作业人员中,男性的FT3和FT4水平高于女性(t=13.859、7.342,均P<0.01),而TSH水平低于女性(t=11.038,P<0.01)。放射作业人员的甲状腺功能与性别有关,与工种和射龄无相关性。结论长期接触低剂量电离辐射会对放射作业人员的甲状腺功能产生一定的影响。Objective To investigate the effects of long-term occupational exposure to low-dose ionizing radiation on thyroid function in radiation workers in Maoming area. Methods Serum levels of free triiodothyronine(FT3),free thyroxine(FT4) and thyrotropin(TSH) were determined by immunochemiluminescence in 1 672 radiation workers who underwent physical examination in Maoming Occupational Disease Prevention and Control Hospital from January to December 2018. A total of 942 health examinees who were exposed to non-ionizing radiation were taken as control group for statistical analysis. Results The levels of FT3 and FT4 in radiation workers were higher than those in control group(t=19.317,4.251,both P<0.01),and the level of TSH was lower than that in control group(t= 6.327,P<0.01).Among radiation workers,the levels of FT3 and FT4 in males were higher than those in females(t=13.859,7.342,both P<0.05),while the level of TSH in males was lower than that in females(t=11.038,P<0.01).Thyroid function was related to genders, while it was found that there was no correlation between thyroid function and different types of work and radiation exposure age. Conclusion The thyroid function of workers exposed to long-term low dose ionizing radiation is affected to some extent.
