中低密度铀钚物料层析伽玛扫描装置(TGS)主要用于测量非均匀核废料和放射性废物中核素及其含量,通过对样品的透射测量和自发射测量数据进行分析得到样品内核素的活度或质量。本工作采用等效径迹长度和蒙卡模拟方法建立近立体角三维自吸收校正因子计算公式。本研究工作自行开发了TGS系统软件,该软件具有参数设置、自动控制、数据获取和数据分析等功能,为了使自
Medium and low density uranium plutonium material tomography (TGS) is mainly used to measure radionuclide and its content in non-uniform nuclear waste and radioactive waste, through the sample transmission and emission measurements were analyzed to obtain the sample nuclide Activity or quality. This work uses the equivalent track length and Mengka simulation method to establish the near solid angle three-dimensional self-absorption correction factor calculation formula. The research work has developed its own TGS system software, which has the functions of parameter setting, automatic control, data acquisition and data analysis.
