Measurement of radioactivity in the environment - Air: radon-222 - Part 7: Accumulation method for estimating surface exhalation rate (ISO 11665-7:2012) 环境中放射性的测量.空气:氡-222.第7部分:估算表面呼气率的累积法（ISO 11665-7-2012）

发布日期： 2013-06-01

本国际标准概述了测量空气中氡-222活度浓度及其短寿命衰变产物的潜在α能浓度的指南。ISO 11665系列的本部分给出了在指定地点短时间（几小时）内测定氡-222表面呼出率的指南。

This International Standard outlines guidance for measuring radon-222 activity concentration and the potential alpha energy concentration of its short-lived decay products in the air. This part of ISO 11665 series gives guidance for determination of the Radon-222 suface exhalation rate during a short span of time (a few hours) at a specified place.
