摘　　要：密封放射源除了广泛用于辐射损伤、放射性测井作业等核技术应用外,工业生产中常用的核仪器仪表,如静电消除器、厚度计、料位计、密度计等在线生产检测设备使用着数量可观的各种密封放射源,本文按照其不同的工作特点和放射源类型,阐述了在工业应用中使用密封放射源的安全防护要点。In addition to radiation injury, nuclear logging and other procedures, sealed sources are widely used in common nuclear apparatus, like static-electrlcity eliminator, thickness meter, level gage and densimeter, in which a considerable number of sealed sources are installed on the online test equipment. This paper describes the primary features of sealed sources in aspects of safety and protection in industry in terms of their characteristics and types.
