, After deposition of a low quantity of sample (0.2 g) on polycarbonate disks, the positions of the ?-emitting particles were first roughly localised with ?-tracks detection. Then, a selection of restricted areas of the deposition disks containing the ?-emitting particles were analysed by Scanning Electron Microscopy (SEM) and characterised with an Energy Dispersive X-ray (EDX) detector. Four uranium particles that likely contained uranium emitted by the FDNPP were identified and characterised. One of these uranium particles was analysed by Secondary Ion Mass Spectrometry (SIMS), and the 235 U/ 238 U and 235 U/ 238 U isotope ratios measured in this particle were characteristic of naturally-occurring uranium, VII.1.1 Abstract The Fukushima Dai-ichi Nuclear Power Plant (FDNPP) released particles containing radionuclides including plutonium and uranium.
