摘要
文章介绍车载式NaI(Tl)大晶体组的γ多道谱仪,该谱仪选用2个10cm×10cm×40cmNaI(Tl)方晶体探头,采用高速ADC集成芯片、USB微控制器等先进技术,具有实时、灵敏度高、识别核素的特点,可用于搜寻失控放射性源、核与辐射突发事件中的快速探察和应急监测、环境辐射调查等工作。
The paper concerns in a vehicle-based NaI(Tl) multiple channel spectrometer. The detector is composed of two NaI(Tl) crystals with the size of 10 cm×10 cm×(40 cm.) The advanced technique are adopted in the system, such as ADC integrate CMOS chip and USB microprocessor. It has specific qualities of high sensitivity, real-time monitoring and distinguishing from the different nuclides, so it can be employed to search the lose radiological sources, investigate radiation in the environment, and to be made use of quickly radiological emergency response involving a terrorist attack or radiological incidents.
