摘要

设计了一套在理想条件下的氡气定向运移实验装置

采用定向测量的方法

对氡气在垂直方向和水平方向的运移进行了测量与计算。结果表明

在水平方向上的运移系数为0.024cm2·s–1

远小于文献给出的氡气在空气中的扩散系数0.1cm2·s–1;垂直向下方向的运移系数为0.182cm2·s–1

明显大于文献给出的氡气在空气中的扩散系数。

Abstract

A directional measurement device has been designed to determine the radon migration in the ideal condition. Both horizontal and vertical migration of radon are studied. The horizontal migration coefficient of radon is 0.024 cm2·s–1

which is much less than 0.1 cm2·s–1

the diffusion coefficient of radon in the air given by the references. The vertical migration coefficient of radon is 0.182 cm2·s–1

which is considerably greater than the diffusion coefficient of radon in the air.
