【摘要】 目的了解杨浦区2009年至2012年不同工种放射工作人员所受外照射剂量水平,为加强放射防护的科学管理提供依据。方法按照职业性外照射个人监测规范要求,用热释光剂量测量的方法进行监测。结果 2009-2012年有效监测工作人员2540人,人均年剂量为0.75 m Sv/a;年剂量<2 m Sv者占监测总人数的99.17%;人均年剂量最大的为核医学工作人员(0.91 m Sv/a)。结论杨浦区放射工作人员的工作环境基本是安全的,应加强核医学和介入放射学人员的防护管理。更多还原

【Abstract】 Objective To assess the personal dosage level of external exposure for radiation workers in yangpu. Methods Thermoluminescence dosimetry was applied to measure the personal external radiation dosage of workers exposed to radiation.Results Totally 2540 radiation workers were monitored from 2009 to 2012. The average annual effective dosage was 0. 75 m Sv / a. The workers receiving annual dosage equivalent less than 2 m Sv accounted for 99. 17%. The average annual individual effective dosage was higher in the nuclear medicine workers than those of other professions. Conclusion Most of the radiation workers in Yang Pu District are safe in the working conditions according to the related national standards. The radiation protection of nuclear medicine should be focused in the future.更多还原
