摘要
选取GM管与NaI(T1)伽马谱仪双辐射探测器作为辐射监测单元,通过软硬件开发,将GPS技术、无线通信技术、核分析技术、放射源定位、剂量率绘图等功能相融合,研制出一套快速灵敏且不受地形限制的远程机载辐射监测系统。测试结果表明:所开发的无人旋翼机机载放射性监测系统在3 km的传输距离下可保持稳定有效的数据通信;机载监测系统的最大可探测距离满足环境辐射监测需求;系统上位机软件实时显示获取的环境辐射数据,并具有轨迹标定、剂量警报、数据查询和分析等功能,为环境辐射评估提供了依据。
Two radiation detectors GM tube and NaI(T1) gamma spectrometer are chosen as radiation monitoring units for the development of remote airborne radiation monitoring systems. GPS technology,wireless communication technology,nuclear analysis technology,radioactive source positioning,dose rate mapping and other functions are combined to develop a drone airborne radiation monitoring system. The experimental results show that the airborne radioactivity monitoring system can maintain stable and effective data communication at a transmission distance of 3 km;the maximum detectable distance of the airborne monitoring system can meet the requirements of environmental radiation monitoring. The upper computer software can display the acquired detection data intuitively,and has the functions of gamma spectra analysis and radiation field analysis,which provides a basis for environmental radiation assessment.
