目的分析评价辖区放射工作人员个人剂量水平,保障放射工作人员健康,为制定相关标准提供依据。方法采用热释光个人剂量测量方法监测,对监测结果按照不同年份、不同职业进行统计和分析。结果云浮市放射工作人员外照射人均年剂量当量为0.39mSv.a-1,呈逐年下降趋势,介入治疗、核医学人均年剂量当量高于其他职业,乡镇级人均年剂量当量高于其他级别。结论云浮市放射工作人员个人剂量水平符合国家卫生标准,但应加强介入治疗、核医学、部分乡镇级卫生院的防护和提高管理人员放射防护意识。
Objective To analyze and evaluate the personal dose level of radiation workers in the area of jurisdiction and ensure the health of radiation workers, so as to provide the basis for formulating relevant standards. Methods The method of personal dose measurement with thermoluminescence was used to monitor and analyze the monitoring results according to different years and different occupations. Results The per capita annual dose equivalent of radiation workers outside Yunfu City was 0.39mSv.a-1, showing a declining trend year by year. Interventional treatment led to a higher per capita equivalent dose of nuclear medicine per capita than that of other occupations. Conclusion The individual dose level of radiation workers in Yunfu City is in line with national health standards. However, interventional care, nuclear medicine, protection of some township-level hospitals should be strengthened and radiation protection awareness of managers should be enhanced.
