摘要
利用小型旋翼机良好的机动性能和环境适用性,将小型旋翼机与传统的核辐射探测设备相结合,再通过软硬件的开发、无线通讯、GPS定位以及核数据处理技术的应用,研发了一套具有受地形环境影响小、可避免人员受到近距离辐射损伤等优点的机载辐射监测系统。介绍了系统的结构组成、工作原理以及关键技术难点,重点研究了系统关键模块的设计以及剂量率响应线性范围的测定。飞行实测结果表明,该系统可对环境中的放射性实时、准确地测量,可用于日常的辐射环境监测以及失控γ放射源的搜寻,为核应急提供了一种新方法。
With excellent mobility and environmental suitability of minitype rotorcraft, which is combined with traditional nuclear radiation detection equipments, a set of airborne radiation monitoring system was implemented by development of hard- ware and software,application of wireless communication,GPS and nuclear data processing technology. The terrain environmental impact on system can be ignored, and radiation damage to workers can also be avoided well. This paper introduces the configura- tion, operating principle and several key technical difficulties of the airborne radiation monitoring system, the design of key mod- ules and measurement of dose rate response linear range are described comprehensively. The test result shows that the system can give a real-time and accurate detection on the radiation of environment, which can be used for daily environmental radiation moni- toring or searching for lost or orphan gamma ray sources. A new method Sor nuclear accidents emergency is provided.
