一些国家正在接受安全管理废辐射源的实际指导和支助据报道,已有约20名无辜公众死于因废辐射源的管理和贮存不当而引起的辐射事故。根据这一背景,国际原子能机构(IAEA)已开展了一系列服务,以帮助那些有兴趣建立有效地安全控制、管理和处置废辐射源的体系的国家。本文主要介绍使用密封辐射源的一些核应用,重点介绍密封源的常见应用,并讨 Some countries are receiving practical guidance and support for the safe management of waste radiation sources It is reported that about 20 innocent public deaths have been reported as a result of radiation accidents caused by the mismanagement and storage of waste radiation sources. Against this background, the International Atomic Energy Agency (IAEA) has implemented a series of services to assist countries interested in establishing a system for the effective and safe control, management and disposal of waste radiation sources. This article focuses on some of the nuclear applications that use sealed radiation sources, highlighting the common applications of sealed sources and discussing
