The Application of LY326 Ion-Spraying Type Atmosphere Radon Detector
Abstract:The purpose of this study is that to test the performance of LY326 ion-spraying type atmosphere radon detector and provided the scientific basis for its application. This paper introduced the functional index of LY326 ion-spraying type atmosphere radon detector. According to different measurement objects RaA and ThC\', Set the corresponding threshold voltage to to distinguish the counts produced by Tn and Rn when measurement of Rn and mixed gas of Rn、Tn. The results show that it has higher sensitivity, shorter measure time, more convenient to carry when compared to FT-648 radon detector by contrast measurement of the school building and Rn, Tn concentration of the surrounding atmospheric, and has great value in Atmospheric radon measurement area.
Keywords: radiation and environment protection radon detector Radon Concentration Thoron
