| Abstract | Pu-containing particles were collected in the Mururoa Atoll at "Safety Trial Test" sites by staff of the International Atomic Energy Agency (IAEA) and other experts. Several particles in the diameter range of 200-1000 µm were first characterized by optical microscopy followed by qualitative and semi-quantitative analysis performed by X-ray microfluorescence technique (µXRF). The elemental distributions for selected elements are also presented. The composition varies greatly not only from particle to particle but also within the same particle indicating a high degree of heterogeneity. The concentrations of Pu range from a few percent to some ppm while other actinide elements, like U and Np, are present at lower concentrations. Other elements, mainly metallic, were also identified at the concentration level of 10-1000 ppm. The elemental maps presented in the paper show the heterogeneous distributions of the elements and correlations between different elemental distributions are observed. The semi-quantitative results presented can be combined with a statistical classification procedure to identify the emitting sources when a limited number of samples are available for analysis. |
