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 understand the health status of radiation workers in petrochemical enterprises and provide basis for radiation protection and management. Methods The data of personal dose and blood of petrochemical workers, liver function, chromosome aberration rate, micronucleus rate, immune function, internal medicine, ophthalmology and dermatology were statistically analyzed. Results The average annual dose of radiation workers was 5. 667mSv · a-1,> 50mSv · a-120. The incidence of hypertension, electrocardiogram abnormality rate, ocular lens opacification rate, leukocyte subnormal, CD4 CD8 ratio abnormality, chromosome aberration rate and the rate of micronucleated cells were higher than those in the normal control group. Conclusion The harm caused by low-dose ionizing radiation to the human body can not be ignored, and the protection of radiologists should be strengthened.
