Quantification and Uncertainty in Particle Morphological Analysis
- Los Alamos National Laboratory (LANL), Los Alamos, NM (United States)
A key part of forensic analysis of interdicted nuclear materials is examining the microstructure of the materials, which are frequently in the form of particulates. We are developing methods for quantifying the morphology of particle sets imaged using scanning electron microscopy. In order to use this data effectively, we need to understand the uncertainties involved in measuring the morphology of particles. This presentation discusses the sources of uncertainty in scanning electron microscopy, and presents the results of an internal user test of the MAMA software package being developed under a DHS Transformational and Applied Research program. The steps required to establish morphological standards similar to NIST standards are discussed.
