Abstract

Mass spectrometry techniques, such as AMS, TIMS and ICP-MS, represent promising techniques for the analysis of artificial radionuclides in environmental samples. They are characterized by high sensitivity, low detection limit, high sample throughput, shorter measuring time compared to conventional radiometric measurements, and the capability to provide isotopic composition information. After the Fukushima Daiichi Nuclear Power Plant accident, an increasing need was recognized for the rapid analysis of accident-released artificial radionuclides (actinides and fission products) in environmental samples for radiation dose estimation and evaluation of effectiveness of radioactive contamination remediation. This review describes the recent progress on mass spectrometric analysis of artificial radionuclides in environmental samples in Japan after the nuclear accident and discusses future research prospects for mass spectrometric techniques in radionuclide analysis.

日本环境样品中人工放射性核素质谱分析的最新进展

质谱分析技术，如AMS、TIMS和ICP-MS，是分析环境样品中人工放射性核素的有前途的技术。它们具有灵敏度高、检出限低、样品通量高、测量时间短、能够提供同位素组成信息等特点。在福岛第一核电站事故发生后，人们认识到越来越需要对环境样品中事故释放的人工放射性核素(锕系元素和裂变产物)进行快速分析，以估计辐射剂量和评价放射性污染补救措施的有效性。本文综述了核事故后日本环境样品中人工放射性核素质谱分析的最新进展，并对质谱技术在放射性核素分析中的应用前景进行了展望。
