摘要
使用半导体γ谱仪,测定由三种典型的稀土原生矿物(离子吸附型稀土矿、氟碳铈镧矿和独居石)及其它矿物生产的稀土产品中γ放射性核素的组成,绘制能量-效率刻度曲线,计算稀土产品中^(227)Ac,^(226)Ra,^(228)Ra,^(138)La等放射性核素的含量。
The paper describes a method of using semiconductor gamma spectrometer to analyse gamma radionuclides content in the rare earth (RE) products from three typical raw materials (ion adsorption type RE ore, bastnasite, monazite), and other ores. The results show that the analytical technique is a simple, convenient and non-destructive method of analysing radionuclides in RE products.
