摘要
云母窗型G-M管能够探测α粒子、β粒子和γ射线。论文建立了云母窗型G-M管测试平台,通过漏计数修正减少了G-M管的死时间影响。分别对α和β放射源进行探测,得到云母窗型GM管对α和β粒子的响应特性,为云母窗型G-M管用于多种射线的探测作了特性研究。
α particle,β particle and γ ray can be detected by mica end window GM tubes.In this paper,the testing platform of mica end window GM tubes is set up.The effect of the dead time of the GM tubes is reduced through the leakage count emendation.In addition,the response characteristics of the GM tubes for α and βparticles are stated through detecting α and β radioactive sources.In conclusion,it is researched that mica end window GM tubes are used in detecting a variety of rays.
