[Analysis of radiation workers health status in a city].

To investigate the health status of radiation workers in a city and provide evidence for the health management of radiation workers. To investigate the health status of radiation workers in a city and provide evidence for the health management of radiation workers. 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, <0.01) and chromosome aberration (χ(2)=75149.737, <0.01) , other radiation sensitive indicators have no difference. The abnormal rate of thyroid function (18.8%) (χ(2)=12.084, <0.01) , micronuclear (0.25‰) (χ(2)=57.359, <0.01) , chromosome aberration (0.08%) (χ(2)=17.209, <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. 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.
