Characterisation and Source Term Assessment of Radioactive Particles from Marshall Islands Using Non-destructive Analytical Techniques
Six plutonium-containing particles stemming from Runit Island soil (Marshall Islands) were characterized by non-destructive analytical and
microanalytical methods. Composition and elemental distribution in the particles were studied with synchrotron radiation based micro X-ray
fluorescence spectrometry. Scanning electron microscope equipped with energy dispersive X-ray detector and with wavelength dispersive system
as well as a secondary ion mass spectrometer were used to examine particle surfaces. Based on the elemental composition the particles were
divided into two groups: particles with pure Pu matrix, and particles where the plutonium is included in Si/O-rich matrix being more
heterogenously distributed.
