摘要
随着核医学快速发展,99m Tc、18 F、131 I等放射性核素引起的内照射污染应引起重视.对两家医院核医学科工作场所开展空气中放射性核素浓度监测,对核医学工作人员开展内照射监测,探讨核医学科内存在放射性核素污染的原因.结果发现,核医学工作场所中存在18 F、131 I气溶胶,未发现99m Tc气溶胶;核医学工作人员体内存在131 I内照射污染;核医学工作人员外照射个人剂量监测结果正常.通过对两家医院核医学工作场所的共同性分析,讨论造成放射性核素污染的原因以及如何避免核医学放射性核素污染.
Abstract
With the rapid development of nuclear medicine,internal exposure caused by 99mTc,18 F and 131 I should be paid attention to.Radionuclide concentration in the workplaces of nuclear medicine department and internal radiation for nuclear medicine staff were monitored in two hospitals.The results of internal personal dose monitoring were compared with external radiation to explore the reasons for radionuclide contamination in nuclear medicine departments.As a result,18 F and 131 I aerosols were found in nuclear medicine workplaces,while 99mTc aerosols were not found;There is 131 I internal radiation contamination in the bodies of nuclear medicine staff;The personal dose monitoring results of nuclear medicine personnel exposed to external radia-tion are normal.By analyzing the commonality of nuclear medicine workplaces in two hospitals,the reasons for radionuclide contamination and how to avoid radionuclide contamination in nuclear medicine department were discussed.
