摘要

本文旨在研究高层建筑室内氡浓度的变化规律

重点研究高度及外界氡浓度对室内氡浓度的影响。本文建立了氡浓度测量的双滤膜实验方法

使用FT-648测氡仪实施氡测量。实验数据的分析中

利用简单物质平衡模型对室内氡浓度与高度

关系以及室内氡浓度与通风率的关系进行了模拟计算。结果表明

在高层住宅建筑三层（9m）以上的高度时模拟计算值与实际测量值符合较好

可以认为高层建筑室内氡的浓度主要由建筑材料所析出的氡决定

但同时也受到通风情况的影响。

Abstract

The paper aims at the study on the indoor radon concentration in high buildings. The two-filter method is chosen as the experimental method to detect radon concentrations by a FT-648 radon counter. The simple mass balance model is used to simulate the relationships among the indoor radon concentration

height

and ventilation rates. The results show a good agreement between the simulation calculation and the measurement data for the height of more than about 9 meters (third floor) in high buildings. This study indicates that the indoor radon concentration in high buildings is decided mainly by the radon emission of building materials and by ventilation rates.
