Several radioactive particles from the Palomares area have been analyzed with the nuclearmicroprobe of the National Accelerator Centre (CNA) in Seville exploring the advantages of combining -PIXE using a 5.5 MeV4He beam with conventional -PIXE analysis using 3 MeV protons. Themeasurements performed with the -particles are more sensitive to the sample surface, while the resultscollected with protons are indicative of the average composition of the hot particle. In this way, importantinformation about the depth distribution of Pu and U in the particles has been obtained. In addition, theparticles have been analyzed by SEM (EDX) and one of them has been sacrificed for the determinationof its U and Pu isotopic composition by ICP-MS and -spectrometry, being gained in this way importantinformation about the composition of the weapons involved in the Palomares accident. |
