Isotopic analysis of uranium particles in environmental samples with SIMS

Esaka, Fumitaka

We are developing particle analysis techniques using secondary ion mass spectrometry for safeguards swipe samples. Isotope ratios of individual uranium particles in the samples taken at nuclear facilities are measured to unveil undeclared nuclear activities. For this purpose, fission track and alpha track techniques are utilized to identify uranium particles and SIMS is used for isotope ratio analysis.
