目的通过对医务放射工作人员外周血淋巴细胞微核4年的检测结果动态分析,探讨微核与工龄、工种之间的关系。方法以广东省某医疗卫生单位接受体检的医务放射工作人员为研究对象,采用常规培养法测定微核率,并按年份、工龄、工种等分类进行微核率比较。结果医务放射工作人员外周血淋巴细胞微核率与工龄等因素有关。结论放射工作人员的微核率随放射工龄的增加呈现剂量累积效应,应加强放射工作人员的防护。
OBJECTIVE: To dynamically analyze the results of 4-year detection of peripheral blood lymphocyte micronuclei in medical radiation workers to explore the relationship between micronucleus and length of service and type of work. Methods The medical radiation workers who received physical examination in a medical and health unit in Guangdong Province were studied. The micronucleus rate was determined by routine culture method. The micronucleus rate was compared according to the year, length of service and type of work. Results The frequency of peripheral blood lymphocyte micronuclei in medical radiation workers was related to length of service and other factors. Conclusions The micronucleus rate of radiation workers shows dose cumulative effect with the increase of radioactive seniority, and the protection of radiation workers should be strengthened.
