标准摘要
[中文适用范围]： 本文件描述了 radon-222 的连续测量方法。 它为连续测量开放或密闭大气中氡活度浓度的时间变化提供了指示。 本文件旨在评估环境、公共建筑、家庭和工作场所氡气活度浓度随通风和/或气象条件等影响量的函数的时间变化。 所述测量方法适用于氡活度浓度大于5 Bq/m3的空气样品。 [外文原描述]： This document describes continuous measurement methods for radon-222. It gives indications for continuous measuring of the temporal variations of radon activity concentration in open or confined atmospheres. This document is intended for assessing temporal changes in radon activity concentration in the environment, in public buildings, in homes and in work places, as a function of influence quantities such as ventilation and/or meteorological conditions. The measurement method described is applicable to air samples with radon activity concentration greater than 5 Bq/m 3 .
