本文件描述了短寿命氡-222衰变产物的综合测量方法[4]。 它给出了测量短命粒子平均势能α浓度的指示 空气中氡-222衰变产物及测量装置的使用条件。 本文件涵盖了从几周到一年不等的时间段内采集的样本。这份文件 不适用于最大采样持续时间小于一周的系统。 所述测量方法适用于具有潜在α能浓度的空气样品 短寿命氡-222衰变产物大于10 nJ/m3，小于1000 nJ/m3。 注:本文件还涉及氡-220衰变产物的情况，仅供参考， 考虑到氡同位素222和220在行为上的相似性。交叉引用:ISO/IEC 17025IEC 61577-1IEC 61577-3ISO 11665-1IEC 61577-4ISO/IEC指南98-3ISO 11929购买本文件时提供的所有当前修订版均包含在购买本文件中。

This document describes integrated measurement methods for short-lived radon-222 decay products[4]. It gives indications for measuring the average potential alpha energy concentration of short-lived radon-222 decay products in the air and the conditions of use for the measuring devices. This document covers samples taken over periods varying from a few weeks to one year. This document is not applicable to systems with a maximum sampling duration of less than one week. The measurement method described is applicable to air samples with potential alpha energy concentration of short-lived radon-222 decay products greater than 10 nJ/m3and lower than 1 000 nJ/m3. NOTE For informative purposes only, this document also addresses the case of radon-220 decay products, given the similarity in behaviour of the radon isotopes 222 and 220.Cross References:ISO/IEC 17025IEC 61577-1IEC 61577-3ISO 11665-1IEC 61577-4ISO/IEC Guide 98-3ISO 11929All current amendments available at time of purchase are included with the purchase of this document.
