In the previous study, we developed a combination method of particle manipulation and secondary ion mass spectrometry (SIMS) for removing the interferences from other elements in other particles. Since the particles were selected randomly and manipulated, it caused the problem not to cover the range of 
U/
U isotope ratio in the sample. In this study, we improved the procedure of analyzing uranium isotope ratios in individual particles by SIMS to cover the range of U/U in the sample.

The safeguards environmental sample analysis by the IAEA requires the development of efficient methods for measuring isotope ratios of ultra-trace amounts of plutonium and uranium particles. We have applied fission track and alpha track techniques to identify of discrimination between plutonium and uranium particles and have successfully measured isotope ratios of the particles using a continuous heating method with a thermal ionization mass spectrometer (TIMS). This method made it possible to find particles containing plutonium and uranium and measure them simultaneously by the TIMS without a chemical separation.

The isotopic composition of Nd is used in a wide range of nuclear field, such as forensic analysis and fuel burnup evaluation, and the currently most used analytical methods include TIMS and ICP-MS. However, the analytical samples obtained in decommissioning of Fukushima's failed reactors contain a mixture of particles of different sources, and these analytical techniques which cannot distinguish individual particles lose the information on their origin and history. Conversely, if the origin can be determined from the burnup of each particle, it is important for clarifying accident progress and criticality safety assessment. For this reason, we have applied ion sputter mass spectrometry imaging, which can measure the distribution of nuclides in individual particles, and have developed laser resonance secondary neutral mass spectrometry as a countermeasure against the isobaric interference. In this study, we performed two-step ionization spectroscopy to obtain highly efficient ionization schemes of Nd. As a result, we found several schemes with higher ionization efficiency than previously reported one.
