无人机航空γ能谱测量在地形高起伏地区异常查证中的应用
Application of the unmanned aerial vehicle-airborne gamma-ray spectrometry system to follow-up geochemical surveys in high-relief areas
摘要
Abstract
In response to the need for large-scale exploration of radioactive minerals in high-relief areas,this study developed an air-borne gamma-ray spectrometer based on small-sized NaI(Tl)crystals,which was integrated with the F-120 unmanned aerial vehicle(UAV)to form an airborne gamma-ray spectrometry(AGRS)system.The UAV-AGRS system was applied to the follow-up geochemi-cal survey of uranium deposits in a certain area of South China.The survey results show roughly consistent locations and morphologies for high-anomaly zones with the ground gamma-ray spectrometry results.Moreover,the results of this study exhibit more detailed anom-aly morphologies,and more significant responses of uranium content-related uranium channel data to known uranium occurrences in the study area,suggesting superior data.Therefore,the UAV-AGRS system shows promising potential as an effective alternative to ground gamma-ray spectrometry for the follow-up geochemical survey of uranium deposits in high-relief areas.关键词
