We thank the editor and two anonymous reviewers for their numerous comments which helped to improve the manuscript. Funding Information: Wenting Bu received his B.S. in Physics from Peking University (China) in 2010 and his Ph.D in nuclear physics and technology in 2015. He participated in a joint study at the National Institute of Radiological Sciences, Japan from 2012 to 2014. He is currently an asso- ciate professor at the Institute of Nuclear Physics and Chemistry, China Academy of Engineering Physics. His research interests radioanalytical chemistry and environ- Youyi Ni is a fourth-year Ph.D. student from the School of Physics, Peking University in China. His study is focused on radiation protection and envi-ronmental radioactivity. Currently he is participating in a joint study program supported by the China Scholarship Council (CSC) and studying at the National Institute of Radio-logical Sciences (NIRS), Japan under the guidance of Dr Jian Zheng. At the NIRS he is devoted to the development of analytical methods for actinides in various environmental samples with ICP-MS as well as the transfer and migration behavior of actinides in the biosphere.

N2 - 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.
