航空伽玛探测器能谱响应规律分析-analysis of energy spectrum response law of airborne gamma detector.docxVIP

IVhave got international advanced level; GR-820 air multi-channel gamma spectrometer was successful introduced, digested and experimental produced, which now play an important role in land resources geological survey.Along with the rapid industrialization of nuclear technology development and accelerated construction of nuclear power, the governments relevant departments have also carried out a series of programs and practices to deal with all kinds of variable conditions. Under the leadership of the relevant departments, Shijiazhuang remote testing center established a national nuclear emergency center, and did a series of exercises work, these rules and regulations are ought to response to the challenge occurring in the future development. gamma spectrometry survey system, due to its characteristics, as the main monitoring nuclear emergency measures, is one of the country much-needed high-tech.Specific study has three aspects: first, in certain circumstances, conduct an aeronautical gamma spectrometry detector response test, use the experimental data for spectrum analysis; second, use Monte Carlo to simulated analysis the performance of the aeronautical gamma spectrometer with the experimental data, and compare with the aeronautical gamma ray spectrometry specifications to provide the appropriate theoretical basis for perfecting the instrument. Third, use Monte Carlo to simulated analysis the performance of the angle responses of aeronautical gamma spectrometer with the experimental data, and compare with the experimental result to conclude.This topic comes from 863 major project Air geophysical survey systems（Major Project No. 2006AA06A200）, mainly aimed the responsibility discipline of the entire aviation spectroscopy, analyze the performance of the instrument even better, There is a profound significance on the studies of theory and practical line, it provides a theoretical basis for the aeronautical gamma ray spectrometry measurement and mineral resources sur
