内容記述 | Uranium-236 is an important anthropogenic radionuclide except for the three main natural uranium isotopes, which could be applied in the fields of environmental tracer, nuclear emergency response, nuclear forensics and nuclear safeguards. Artificial 236U is mainly generated through neuron absorption of nuclear fuel 235U after neuron irradiation. Therefore, the isotopic ratios of 236U with other uranium isotopes (fingerprints) are different regarding the different nuclear fuel age. Also, the corresponding fingerprints are different in different types of nuclear reactor. The operation statue of nuclear reactor, the source of nuclear material and the migration of released radionuclides in environment could be studied by analyzing the isotopic ratios of 236U/238U and 236U/235U in the corresponding samples. Since 236U is a minor isotope and its concentration is extremely low in nuclear material and environmental samples, it is important to accurately analyze the isotopic ratios for its application in the environmental tracer, nuclear emergency response, nuclear forensics and nuclear safeguards. In this review, we summarized the development of sample pretreatment and analysis technologies for 236U measurement in recent years, especially focused on the development of 236U isotopic ratio analysis using mass spectrometry. In the meanwhile, the research progress of 236U application in the fields of nuclear safeguards and environmental tracer was also reviewed. The research prospect for 236U analysis and application was also proposed. | |||||
