在已知铀的分析方法中,除活化分析外,荧光法是最灵敏的,因此它被广泛地用于测定各种矿石、矿物、陨石、水、土壤、淤泥、植物和动物组织中的微量铀。但要适用于各种矿石和矿物的测定(1×10~(-4)%),荧光法的灵敏度常常达不到,尚有许多问题需要解决,而活化分析方法需要包括中子源的复杂设备,因 In the known uranium analysis method, the fluorescence method is the most sensitive except for the activation analysis, and thus it is widely used in the determination of trace amounts in various ores, minerals, meteorites, water, soil, silt, plants and animal tissues uranium. However, it should be applied to the determination of various ores and minerals (1 × 10 -4%). ​​The sensitivity of the fluorescence method is often not reached. There are still many problems to be solved, and the activation analysis method needs to include the complexity of the neutron source Equipment, due
