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-1 20.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 CD4/CD8, 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.
