Abstract
Analysis of dust samples from uranium enrichment facilities :is focused on the detection and analysis of uranium-containing particles. A chemical and isotopic analysis of individual particles from dust samples is thought to b e an effective analytical tool to check the absence of nuclear-weapon produ ction activities. The used different analytical techniques from individual laboratories have to be verified with respect to their uncertainties and li mits of detection, This requires a well-characterized uranium micromass sta ndard, composed of particles with a narrow spread in the uranium mass distr ibution. In this work the relative uranium mass distribution is determined of a set of U3O8 micro particles. The measured set of particles is monodisp erse with a standard deviation of the relative uranium mass distribution of 16%. (C) 1999 Published by Elsevier Science B.V. All rights reserved.
