核探测中的车载γ能谱技术

Nuclear Exploration of Car-Borne γ-ray Spectrometry

    摘要
  • 摘要: 车载γ能谱是核探测方法之一，应用于放射性矿产资源探测、核辐射环境和核应急领域。通过标准模型采用矩阵法或剥谱法计算车载γ能谱所确定的核素含量。通过铀变异系数，活化铀和差量铀，铀的富集系数，铀、钍、钾的GRB合成成像，铀成矿有利指数U1，全谱分解分形，综合预测等方法的应用研究，表明车载γ能谱技术在铀资源勘查中的显著效果，同时为核辐射环境探测提供方法基础。

     

    Abstract: Car-borne γ-ray spectrometry is a nuclear exploration, used in detecting radio-active mineral resource, nuclear environment and nuclear accident. Car-borne γ-ray spectrum for element concentration determination can be calculated through standard pad by matrix or stripping ratios method. Application study on uranium variation coefficient, activated uranium, dispersion uranium, enrichment coefficient of uranium, RGB, U1, full spectrum of decomposing and fractal method, integrated assessment, and so on was performed. The results show that the technique of car-borne γ-ray spectrometry is helpful to uranium resources exploration which can be used in nuclear environment.
