无人机载核辐射监测系统研究

Research on Nuclear Radiation Monitoring System of UAV

在核设施发生重大核事故后,快速进入事故区域获取核泄漏及放射性污染现场的辐射分布情况具有重要意义。当重大核事故发生后,通常伴随道路的严重损毁,致使核辐射探测器无法随人员和车辆通过地面通道进入核事故现场进行辐射监测。为了克服传统的核应急监测方式易对人员辐射伤害、机动性差及效率低等问题,本研究设计并实现一种无人机载辐射监测系统,能够迅速进入放射性污染区域上空进行辐射监测。无人机辐射监测系统主要包括宽量程G-M计数管、溴化铈闪烁体探测器、数据采集系统与数据传输系统,将以上装置搭建在无人机上可执行0~100 m的低空实时辐射剂量率和能谱测量任务。

After a major nuclear accident occurs in a nuclear facility,it is of great significance to quickly enter the accident area to obtain the radiation distribution of the site of nuclear leakage and radioactive contamination.In order to overcome the traditional nuclear emergency monitoring methods,which are prone to radiation damage to personnel,poor mobility and low efficiency,this paper designs and implements a UAV radiation monitoring system,which can quickly enter the sky over radioactive contaminated areas for radiation monitoring.The UAV radiation monitoring system mainly includes wide-range G-M counter tube,cerium bromide scintillator detector,data acquisition system and data transmission system.The above devices can be built on the UAV to measure the real-time radiation dose rate and energy spectrum at 0-100 m low altitude.
