Radioactive Measurement Methods In Uranium Exploration Applied Research

As the basic fuel for nuclear energy utilization,uranium occupies a relatively important position in China's resource category,and its radioactive geophysical characteristics are obvious.Therefore,it is a common and extremely effective method to use its radioactive characteristics of ore body to find ore.The Jiayin region of Heilongjiang is a medium-and low-mountain forest area with severe vegetation coverage and a low degree of uranium exploration.This research focuses on the use of multiple radioactive comprehensive measurement techniques to conduct applicability research in the area,filling the gap in uranium exploration in the area.It has certain guiding significance for further uranium exploration in this area.In this study,the first use of aviation gamma spectroscopy measurement data(mainly converted to uranium content data)for a comprehensive analysis,delineating the prospect of mineralization.Secondly,ground gamma-ray spectral area measurement is used to study the characteristics of uranium anomaly distribution in key areas.Then use trough exploration to verify the abnormal parts and analyze the causes of uranium anomalies.In addition,the audio-frequency magnetotelluric survey was used to study the main fault structure features in key areas,which provided further evidence for the research work in this area.The summary summarizes the favorable factors of uranium mineralization in this area,and provides a basis for further uranium exploration in this area.(1)This time the analysis and research were carried out using aviation gamma spectroscopy data,and the Moshishan area was delineated as a volcanic rock uranium metallogenic prospect in the Jiayin Basin.(2)This time,the ground gamma spectroscopy measurement method was used to identify the distribution and distribution characteristics of uranium anomalies in the Moshishan area.A total of 1 uranium anomaly zone and 1 anomaly point were delineated.(3)By exposing uranium anomalies and using directional radiation measurement and analysis,it is possible to accurately analyze the causes of uranium anomalies.(4)Through comparative analysis,it summarizes the favorable factors of uranium mineralization in Moshishan area of Jiayin Basin,which provides a basis for further uranium exploration in this area.(5)Comprehensive use of multiple radioactive measurement methods can achieve better uranium ore prospecting results.
