The development of portable nuclear spectrometer based on STM32F103 chip was introduced .including that of VB-based nuclear spectrum processing software,in which,the controller has the collected data analyzed before having them transmitted to the display module and memory card. Testing with Nal ( Tl) crystals proves its better performance in acquisition accuracy and sensitivity,etc.%介绍了一种基于STM32F103芯片的便携式核谱仪的研制,控制器对采集的数据进行分析处理后将数据发送到显示模块,并将数据发送到存储卡上.并且介绍了基于VB开发环境的核谱处理软件的开发设计.用NaI (Tl)晶体做实际测试后,系统在采集精度、灵敏度等主要技术指标上获得了满意的效果.
