Isotope ratios in individual U and Pu particles give valuable information on nuclear activities. We have developed SIMS and FT-TIMS methods to determine uranium isotope ratios in individual particles. Now, we are developing a technique to measure individual Pu particles. In this presentation, these analytical techniques will be displayed.
