基于蓝牙4.0的微型核辐射剂量计设计

摘要

针对目前个人核辐射剂量监测手段便携性差、实时性较差和持续监测能力不足等问题,设计了一种基于蓝牙4.0模块的微型低功耗核辐射剂量计;系统使用计数管探测辐射粒子,充分利用了MSP430混合信号处理器和蓝牙4.0模块的低功耗特性,体积小巧、续航能力强、运行稳定可靠;该剂量计配合手机APP即可单独使用,又可多台组网使用,可为人员提供持续可靠地实时剂量率监测和个人剂量分析,在核工业及核医学个人防护领域具有广阔的应用前景.%Based on MSP430 mixed signal processor and Bluetooth 4.0 module,this paper designed a micro nuclear radiation dose rate monitor to improve its portability,real time feature and the ability of continuous monitor.The system used a G-M counter to detect the radiation particles,and it was designed smart,continuous and reliably by take advantage of the Ultralow-power feature of the MSP430 and Bluetooth 4.0 module.The micro monitor could provide sustained and reliable real-time dose rate monitoring for person and personal dose analysis by using a smartphone APP either single or multiple and has wide application prospects in the field of nuclear industry and nuclear medicine personal protection.
