导言近年来,γ射线闪烁谱仪已成为分析铀、钍矿石的有力工具,它能给出矿石不平衡状态和共生顺序的有价值的、立即可分辨的数据。而与化学方法相比,仍保留对样品粉未不作处理的优点,从而节省分析时间和费用。我们最感兴趣的是~(238)U 和(232)Th,它们是α发射体,并伴随有微弱的低能γ射线。因为 Introduction In recent years, γ-ray scintillation spectroscopy has become a powerful tool for the analysis of uranium and thorium ores, which gives valuable, immediately distinguishable data on the ore imbalances and symbiotic sequences. Compared with the chemical method, the advantages of not treating the sample powder are still retained, thereby saving analysis time and cost. We are most interested in ~ (238) U and (232) Th, which are alpha emitters with weak low-energy gamma rays. because
