摘要

针对空气氡浓度测量需灵敏度高、稳定性好、能区分氡钍等特点

设计了一种基于空气氡静态扩散静电累积原理的α能谱测量装置及讨论了主要影响因素

并提出初步解决办法和进行了相应的实验。经过标准氡室的刻度

得到测量装置的能量刻度曲线、能量分辨率和测量灵敏度等重要信息。实验数据表明该方案理论可行

性能符合相关国家标准规定的对空气氡浓度检测的要求。

Abstract

Background: Radon is one radioactive gas which should be monitored.Purpose: High sensitivity

good stability for distinguishing the characteristics of radon and thorium in air radon content measurement are required.Methods: One alpha energy spectrum measuring device was designed based on diffusion-accumulation theory.And the major influence factors were discussed.At the same time

the preliminary solution was proposed and testing was progressed.Results: We have got the results of energy calibration curve

energy resolution

sensitivity and other important information by standard radon chamber calibration.Conclusions: The experimental results show that this scheme is feasible and the performance is suited to the national standards for air radon measurement requirements.
