摘要
为探索研究反康技术在γ能谱测量应用中的规律及有效性,在实验室利用CSS-D-60型反康普顿γ能谱仪系统进行了铀矿标物的反康测量研究,分别针对铀钍混合、铀镭平衡和单钍粉末样品进行了实测统计,获取了各类样品中186～1847 keV能量段的康普顿散射光子在实测谱中的占比分布.实验结果表明,反康普顿修正数据占比随着能量的增加呈上升趋势,在1 001 keV能峰处的修正百分占比超60％.研究成果能够为γ能谱测铀技术装备的研发提供重要数据借鉴.
Abstract
To explore the effectiveness and application of anti-Compton technology in γ spectrum measurements,an anti-Compton measurement study of uranium ore standards was conducted in the laboratory using the CSS-D-60 type anti-Compton γ spectrometer system.Specific measurements were taken for mixed uranium-thorium,uranium-radium equilibrium,and single thorium powder samples.The proportion distribution of Compton scattering photons in the measured spectrum in the energy range of 186-1847 keV for these various samples was obtained.The experimental results show that the proportion of anti-Compton correction data increases with energy,and the correction percentage at the 1001 keV energy peak,which is of interest in direct uranium measurement technology,exceeds 60％.The research results can provide important data references for the development of γ spectrum-based uranium measurement technology and equipment.
