核医学工作人员内照射剂量监测研究进展

Ongoing research on monitoring of internal exposure of nuclear medical staff

随着核医学应用的广泛开展和相关工作人员的增多,潜在的职业健康问题也应该受到足够重视。目前,大多核医学放射工作人员的个人剂量监测主要是通过热释光剂量计等提供的外照射信息,并未全面开展常规内照射的监测,这可能会低估他们的年有效剂量。全面的个人剂量监测是职业健康监护的重要内容,也是职业健康管理的重要手段。本文分析了核医学内照射的特点,介绍了核素的监测技术和剂量估算方法,列出了几种常用软件,从而全面客观了解和认识当前核医学工作人员的内照射相关内容,为卫生行政部门制定监管政策及防护要求提供参考。

With the wide application of nuclear medicine and the increase in the number of related staff,the potential occupational health problems should receive enough attention.At present,the personal dose monitoring of most radiation workers in nuclear medicine is mainly based on the information on external exposure provided by thermoluminescence dosimeters whereas the routine internal exposure monitoring has not fully been carried out,thus resulting in underestimating their annual effective dose.Comprehensive personal dose monitoring is not only an important part of occupational health monitoring,but also a crucial means of occupational health management.In this paper,the characteristics of internal exposure in nuclear medicine were analyzed,the monitoring techniques and dose estimating method were introduced,and several commonly used softwares were listed,so as to comprehensively and objectively learn about the current internal radiation exposure of nuclear medicine workers,and to provide reference for health administration departments to formulate regulatory policies and protection requirements.
