摘要

本文采用 2只扩散杯

一只选择渗透率较大的滤膜

使2 2 2 Rn和2 2 0 Rn能很容易的进入。另一只选择渗透率较小的滤膜

该滤膜只允许2 2 2 Rn进入

半衰期较短的2 2 0 Rn被阻挡在外面。通过不同滤膜扩散率的差异

改变探测器的空气交换率

从而达到同时测量2 2 2 Rn和2 2 0 Rn的目的

Abstract

A passive integrating dosimeter with two diffusion cups was applied for detecting 222 Rn and 220 Rn simultaneously. To let both nuclides enter in easily

one of the cups had membrane with higher permebility. However

the other cup with lower permeability membrane could only allow the entering of 222 Rn. Hence

222 Rn and 220 Rn can be detected simultaneously by such dosimeters.
