Summary
In the event of a 238Pu release incident, establishing the particle size range of the material is imperative to understand why the release occurred, determine the extent of dispersion, and provide key parameters for dose estimates in cases where inhalation exposures occur. These are often challenging measurements due to the combination of small particle size and low number of particles in any single sample. Here we improve and expand upon previous work combining autoradiography and scanning electron microscopy (SEM) with energy dispersive x-ray spectroscopy (EDS) automated particle analysis (APA) software to locate, characterize and determine the particle size distribution of trace 238PuO2 particles.
