| Sumario: | More than 30 years after the occurrence of an aircraft accident which involved the detonation of two nuclear weapons in the surrounding area of the village of Palomares (Spain), the affected terrestrial area has been investigated for remaining transuranic contamination. Evidence from the presence of this contamination was initially found through the analysis of the 241Am inventories in superficial soil samples collected in the region, and was confirmed through the analysis of the 239 + 240Pu inventories and their associated 238Pu/239 + 240Pu activity ratios in the same samples. However, it was also observed that a considerable fraction of the remaining contamination in the area was present in particulate form, i.e. as “hot particles”. The work performed in our laboratory for identification, isolation and characterisation of these “hot particles” as well as some conclusions obtained from these analyses are outlined in this paper. |
