摘要
目的 了解石油化工企业的放射工作人员健康状况 ,为辐射防护和管理工作提供依据。方法 通过对石化放射工作人员的个人剂量和血象、肝功能、染色体畸变率和微核细胞率、免疫功能、内科、眼科及皮肤科检查的资料进行统计学处理。结果 放射工作人员年均剂量 5. 667mSv·a- 1 ,>5 0mSv·a- 1 2 0人次。放射组高血压发病率、心电图异常率、眼晶体混浊率、白细胞低于正常者、CD4 CD8比值异常者、染色体畸变率和微核细胞率高于正常者 ,明显高于对照组。结论 低剂量电离辐射对人体造成的危害不容忽视 ,应加强对放射人员的防护。
Objective To investigate the health condition of the people who work in the petrochmical field and to provide the basis for the policy-making of control and survey of the radiology disease. Methods To measure the volume of radioactivity individual in the enviroument of the people who work in the field of petrochemistry and consequently to cheek and analysize the changes in physical and biochemitry. Results The annual volume of radioactivity exposure individual is 5.667 mSv·a -1,>50 mSv·a -120. Conseqently, this volume can induce many abnormalities in human body. Compare to the control group, the abnormalities include high blood pressure of abnormal EKG, eye disease, low white blood ceels, the changed rate of CD 4/CD 8, distortion of DNA and appearances of higher micronucluus.Conclusion Long time exposure to low volume of radiation will cause some of the abnormalities to humanbody. Therefore, the health protection measures should be strengthened.
