环境样品中核素钚的分析方法和研究展望

The Analytical Method of Radionuclide Pu in Environmental Samples and Research Prospect

本文介绍了人工放射性核素Pu的辐射特性、环境水平和来源,讨论了核素Pu的环境样品的前处理、分离和提纯方法、化学产额示踪剂的选择以及其放射性能谱分析技术(α能谱和液体闪烁计数器)和质谱分析技术(电感耦合离子质谱,热电离质谱,共振离子质谱和加速器质谱)在测定时需要考虑的一系列问题,最后概括了核素Pu在环境地球化学中的应用方向。

This paper dealt with the radiation characteristics, environmental concentrations, and the source of artificial radionuclide Pu, and described the pre-treatment, separation, and purification of environmental samples. The radiometric methods, alpha-spectrometry, liquid scintillation counters, and mass spectrometric methods, inductively coupled plasma mass spectrometry, accelerator mass spectrometry, thermal ionization mass spectrometry, and resonance ionization mass spectrometry were re- viewed for the determination of plutonium. Finally, the research prospect was summarized.
