The Fukushima nuclear accident caused the release of large amounts of radionuclides into the environment. After the accident, radioactive contamination assessment in environmental samples is essential for radiation dose estimation and radioactive remediation. Mass spectrometry characterized by high sensitivity, low detection limit, short measuring time, high sample throughput, and the capability to obtain atomic ratios is a promising technique for the analysis of the accident released long-lived radionuclides. This review describes the developed analytical methods based on mass spectrometric techniques for the determination of radionuclides (Pu isotopes, U isotopes, radiocesium, radioiodine, radiostrontium, etc.) with regards to Fukushima samples. The real applications of mass spectrometric techniques for radioactive source identification, radiation protection and geochemical tracing are discussed to highlight the importance of mass spectrometric techniques in radioactive contamination assessment after the accident. Future research prospects of mass spectrometric techniques for the analysis of radionuclides with application to Fukushima samples are briefly outlined.

质谱在福岛核事故后放射性污染评估中的作用

福岛核事故导致大量放射性核素释放到环境中。事故发生后，环境样品中的放射性污染评估对于辐射剂量估算和放射性修复至关重要。质谱法具有高灵敏度，低检测限，测量时间短，样品通量高以及能够获得原子比的特点，是分析事故释放的长寿命放射性核素的有前途的技术。这篇综述描述了基于质谱技术开发的用于测定放射性核素（Pu同位素，U同位素，放射性铯，放射性碘，放射性锶等）的分析方法。）有关福岛样品的信息。讨论了质谱技术在放射源识别，辐射防护和地球化学示踪中的实际应用，以突出质谱技术在事故发生后放射性污染评估中的重要性。简要概述了用于放射性核素分析的质谱技术在福岛样品中的应用前景。
