Abstract Objective To Study the influence on the professional workers for long-term exposure to low-dose ionizing radiation,and provide scientific basis for further radiation protection.Method 530 radiation-exposed and 87 healthy workers were chosen for the clinical examination and laboratory test.Results Personal annual effective doses were 1.47mSv,the symptoms of neurasthenia,skin lesion and lens opacity were more serrious than those of the control group,the prevalence increased as working period prolonged.The leukocyte and platelet count was lower than that of the control group.The aberration rate of lymphocytes chromosomas and the rate of micronucles were both significantly higher than that of the control group,and the rate increase as working period prolonged.Conclusion Long-term and low-dose radiation exposure may cause certain radiant injures and radiation protection should be further improved.
