【Abstract】 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.更多还原
