| Abstract: | An alpha spectrum measuring instrument which is used to measure radon exhalation rate is introduced in this paper, it combines software with hardware together to ensure spectrum stabilization and repeatability. It can detect different nuclides according to different measuring requirements so as to avoid contaminating the detector and save measuring time. The system operation and measuring spectrum soft- ware are combined together on windows interface and easy to operate, it displays full range spectrum. The paper introduces the structure, performance, control the influence of temperature and humidity, tion rate, and spectrum analysis. characteristics of the instrument and the method to measuring mode, conversion method of radon exhalation rate, and spectrum analysis. |
