摘　　要：参照国内外航空γ能谱测量校准标准和IAEA有关权威技术文献,利用国内现有的航空γ谱仪系统校准条件,对目前属国际上先进的一套航空巡测γ谱仪系统开展了系统性的校准工作。介绍了航空巡测γ谱仪系统的性能和机载安装,对基本校准内容和涉及的重要参数,如宇宙射线、系统本底、大气氡本底、天然放射性核素及人工放射性核素137Cs和60Co等,进行了科学的校准,给出了校准数据的正确使用方法和应用条件。Based on the corresponding standards and technical documents of the National Standardization Organizations,International Atomic Energy Agency as well as available calibration conditions at present,the calibrations of a type of advanced airborne gamma-ray spectrometry has been carried out in this paper. The basic configuration and installation of the spectrometry are introduced. The important parameters of basic contents in calibration such as cosmic,aircraft background, atmospheric radon,natural radionuclide and Cs-137 and Co-60 are determined, and how and what kinds of radiation field to use these calibrated data are discussed here.
