Objective: To investigate the health status of radiation workers in a city and provide evidence for the health management of radiation workers. Methods: To investigate the health status of radiation workers in a city and provide evidence for the health management of radiation workers. Results: The majority of radiation workers are engaged in diagnostic radiology, male is more than female. The abnormal rate of micronuclear (0.59‰) and chromosome aberration (0.47%) was highest in nuclear medicine workers. The abnormal rate of micronuclear and chromosome aberration was similar with interventional and diagnostic radiology. Expect for micronuclear (χ(2)=32.945, P<0.01) and chromosome aberration (χ(2)=75149.737, P<0.01) , other radiation sensitive indicators have no difference. The abnormal rate of thyroid function (18.8%) (χ(2)=12.084, P<0.01) , micronuclear (0.25‰) (χ(2)=57.359, P<0.01) , chromosome aberration (0.08%) (χ(2)=17.209, P<0.01) in group whose service length exceeding 20 years was higher than other service length groups. There is no statistical difference in other radiation sensitive indicators among different service length group. Conclusion: Long-term low doses of ionizing radiation could affect radiation worker's health, expecially radiation workers engaged in nuclear medicine and radiotherapy. We must pay attention to occupaitonal health care and management to ensure radiation worker's health.
目的： 掌握某市放射工作人员健康状况，为放射工作人员职业健康管理提供依据。 方法： 于2016年11月到2017年10月，选择某市放射工作人员752名，汇总分析其职业健康检查资料中外周血象、甲状腺功能、晶状体、微核和染色体畸变等职业健康检查项目。 结果： 放射工作人员以诊断放射学放射工作人员居多，男性多于女性。核医学放射工作人员微核率为0.59‰和染色体畸变率为0.47%最高，放射诊断与介入放射学放射工作人员相似。除微核（χ(2)=32.945，P<0.01）和染色体畸变（χ(2)=75 149.737，P<0.01）外，不同工种间其他辐射敏感指标差异无统计学意义（P>0.05）。>20年工龄组放射工作人员甲状腺功能异常率为18.8%（χ(2)=12.084，P<0.01）、微核率为0.25‰（χ(2)=57.359，P<0.01）和染色体畸变率（0.08%）（χ(2)=17.209，P<0.01）高于其他工龄组，其他辐射敏感指标各工龄组间差异无统计学意义（P>0.05）。 结论： 长期低剂量电离辐射对放射工作人员的健康有一定影响，尤其是长期从事核医学和放射治疗放射工作人员，应重视其职业健康监护与管理，保障放射工作人员的健康。.
