标准摘要
[中文适用范围]： 本标准规定了各类建筑物氡活度浓度的测定要求。 建筑物可以是单户住宅、公共建筑、工业建筑、地下建筑等。 本文件描述了在初步调查阶段评估建筑物中氡年平均活度浓度的测量方法。 它还涉及确定建筑物内氡气的来源、进入路线和转移路径所需的调查（附加调查）。 最后，本文件概述了对已实施的缓解技术进行缓解后立即测试、监测其有效性以及测试建筑物对氡行为的可持续性的适用要求。 本文件不涉及技术建筑诊断或缓解工作的规定。 [外文原描述]： This document specifies requirements for the determination of the activity concentration of radon in all types of buildings. The buildings can be single family houses, public buildings, industrial buildings, underground buildings, etc. This document describes the measurement methods used to assess, during the initial investigation phase, the average annual activity concentration of radon in buildings. It also deals with investigations needed to identify the source, entry routes and transfer pathways of the radon in the building (additional investigations). Finally, this document outlines the applicable requirements for the immediate post‑mitigation testing of the implemented mitigation techniques, monitoring of their effectiveness and testing of the sustainability of the building's behaviour towards radon. This document does not address the technical building diagnostic or the prescription of mitigation work.
