摘要

氡浓度及氡子体ɑ潜能浓度测量已得到广泛的关注

本文介绍了"马尔科夫法"氡子体潜能浓度测量的基本原理

以及按此设计的气球法测氡仪的硬件和软件。系统对金硅面垒半导体探测器和直流真空刮片泵进行了整合

设计了气路切换阀

无需取下气球即可方便的改变气路方向。仪器逻辑控制采用嵌入式ARM7微处理器

配备了温度、湿度传感器

能够存储2000组测量数据。仪器在南华大学标准氡室进行了测试

结果表明新研制的气球法测氡仪使用简便、性能稳定、结果可靠。

Abstract

Nowadays

the measurement for radon concentration and radon daughters potential ɑ energy concentration has gained more and more attention.This paper introduces the basic principle for ’Markov’ method in details.A hardware and software of the radon measure instrument by balloon has also been described.This system integrated Au-Si surface barrier detector and dc vacuum pump and designed a pneumatic switch valve.With the switch valve

the direction of gas path can be changed conveniently without the balloon being taken down.This instrument has an internal temperature and humidity sensor and ARM7 microprocessor as the logic core.It can store 2000 groups of data in the system.Meanwhile this Radon instrument has been tested in standard radon chamber of South China University and the results showed that the new developed balloon method measure radon apparatus could be applicable because of its easy use

great reliability and performance stability.
