标准摘要
[中文适用范围]： 本文件规定了密封源的不同泄漏测试方法。 它提供了一套使用放射性和非放射性手段的综合程序。 本文件适用于以下情况： ——根据 ISO 2919[1] 进行设计分类测试后的测试源泄漏测试； ——密封源的生产质量控制测试； ——在工作寿命期间，定期对密封源进行定期检查。 本文件的附录 A 指导用户根据情况和来源类型选择最合适的方法。 人们认识到，在某些情况下可能需要进行本文件中未描述的特殊测试。 但需要强调的是，就密封放射源的生产、使用、储存和运输而言，遵守本文件并不能代替遵守国际原子能机构相关法规[17]和其他相关国家法规的要求。 人们还认识到，各国可以根据密封源类型、设计、工作环境和活动制定法定法规，指定测试豁免（例如，对于总活动低于泄漏测试限值的极低活动参考源） 。 [外文原描述]： This document specifies the different leakage test methods for sealed sources. It gives a comprehensive set of procedures using radioactive and non-radioactive means. This document applies to the following situations: — leakage testing of test sources following design classification testing in accordance with ISO 2919 [1] ; — production quality control testing of sealed sources; — periodic inspections of the sealed sources performed at regular intervals, during the working life. Annex A of this document gives guidance to the user in the choice of the most suitable method(s) according to situation and source type. It is recognized that there can be circumstances where special tests, not described in this document, are required. It is emphasized, however, that insofar as production, use, storage and transport of sealed radioactive sources are concerned, compliance with this document is no substitute for complying with the requirements of the relevant IAEA regulations [ 17 ] and other relevant national regulations. It is also recognized that countries can enact statutory regulations which specify exemptions for tests, according to sealed source type, design, working environment, and activity (e.g., for very low activity reference sources where the total activity is less than the leakage test limit).
