【Abstract】 In order to use UAV platform to carry out the airborne γ spectrum anomaly inspection for uranium exploration, the ultra-low altitude UAV-borne γ spectrometry technology was developed by using the selfdeveloped equipment and calibration method. The uranium anomaly inspection measurement and data processing were carried out, and the important information of uranium anomaly shape, scale and amplitude were found out in detail. By comparing the results of airborne γ spectrometry and ground portable γspectrometry, it was concluded that the ultra-low altitude UAV-borne γ spectrometry was basically consistent with the ground measurement results, but more efficiency. The ultra-low altitude UAV-borne γ spectrometry is expected to replace the existing ground portable γ spectrometry to carry out uranium anomaly inspection in ultra-low altitude flying areas such as grassland and desert.更多还原
