标准摘要
[中文适用范围]: 本文件介绍了对核设施运行和退役期间产生的气态流出物中的氚和碳 14 进行采样的方法和规定。 具体包括样本提取位置、提取、运输流量测量以及收集以供后续分析。 本文件不涉及烟囱和管道排出空气中氚活度和碳 14 活度的实时测量。 有关实时测量的信息可以在氚和碳 14 排放的样品处理、分析和计算中找到,这些信息将在 ISO 20041 的未来部分中解决。 [外文原描述]: This document presents the methods and provisions for sampling tritium and carbon‑14 in the gaseous effluents generated by nuclear facilities during operation and decommissioning. Specifically included are sample withdrawal location, extraction, transport flow measurement, and collection for later analysis. This document doesn’t address to real time measurements of tritium activity and carbon-14 activity in the effluent air of stacks and ducts. Information about real time measurements can be found in ISO 2889:2021, Annex H. Sample processing, analysis and calculations of tritium and carbon‑14 emissions will be addressed in future parts of ISO 20041.
