Based on the first airborne gamma ray spectrometer on the drone in China,this paper briefly described related techniques such as principle,calibration, measurement,and data processing.Through the demonstration surveys in both Karamay and Kashi,rich results of aero radiometric survey were obtained.Combined with regional geology,remote sensing data,radioactivity characteristics of rocks and the results of ground-checking,the authors analyzed and evaluated the regional features and the local anomalies of aero-radiometric survey comprehensively.The results show that the technique is an effective method in such aspects as basic geological investigation and exploration of radioactive and non-radioactive mineral resource.Finally,the measurement technique was evaluated briefly for the drone based on the fix-wing craft.
