Description

We examined the performance of ICP quadrupole mass spectrometry regarding U-234, 235 and 238 isotope ratio measurement in nano-gram uranium samples, thorough analysis of fourteen soil samples from a nuclear test site. The study was motivated by the need to analyze the minor uranium isotopes in exhibitions in Hiroshima Peace Memorial Museum, with minimum consumption of precious historic samples. The comparison of the obtained U-235/U-238 and U-234/U-238 data between our group and a national laboratory in US showed that the relative discrepancy was <0.5% and <2% when 16-40 ng uranium was used for the analysis.
