标准范围

ISO的范围？16659系列旨在提供不同的测试方法，旨在评估核设施通风系统中放射性碘捕集器的效率。ISO？16659系列处理含有固体吸附剂的碘阱？-主要是活性和浸渍木炭，核设施通风系统中最常用的固体碘吸附剂？-以及用于特殊条件的其它吸附剂(例如高温沸石)。本文件的范围是为工业核设施的不同测试方法提供一般和通用的要求。不同的方法将在ISO的其他具体部分描述？16659系列。核医学应用被排除在ISO范围之外？16659系列。原则上，ISO？16659系列主要用于过滤放射性碘，但其他放射性气体也可以与碘一起被捕获。在这种情况下，在ISO的特定部分中，可能必须对这些其他放射性气体进行一些特定的调整？16659系列。本文件描述了主要的一般要求，以便根据尽可能可重复的测试条件原位检查碘阱的效率。

The scope of ISO 16659 series is to provide different test methods aiming at assessing the efficiency of radioactive iodine traps in ventilation systems of nuclear facilities. The ISO 16659 series deals with iodine traps containing a solid sorbent — mainly activated and impregnated charcoal, the most common solid iodine sorbents used in the ventilation systems of nuclear facilities — as well as other sorbents for special conditions (e.g. high temperature zeolites).

The scope of this document is to provide general and common requirements for the different test methods for industrial nuclear facilities. The different methods will be described in other specific parts of ISO 16659 series. Nuclear medicine applications are excluded from the scope of ISO 16659 series.

In principle, ISO 16659 series is used mainly for filtering radioactive iodine, but other radioactive gases can also be trapped together with iodine. In such a case, some specificity may have to be adapted for these other radioactive gases in specific parts of ISO 16659 series.

This document describes the main general requirements in order to check in situ the efficiency of the iodine traps, according to test conditions that are proposed to be as reproducible as possible.
