Comparison of techniques to localise U-bearing particles in environmental samples

This publication shows results of a comparison of three techniques for localising radioactive, and U-bearing particles in contrasted samples. Particles are localised by the means of three methods: (1) Fission Tracks (FT), (2) Imaging Plate (IP), and (3) real time autoradiography (BeaQuant (R)). These techniques were applied to various samples, including a sediment sampled in the vicinity of the Fukushima Dai-Ichi Nuclear Power Plant (FDNPP) and a sample made of pure U oxide particles. In addition, the efficiency of the combination of two methods (FT and IP) to localise specifically anthropogenic U-bearing particles was tested.
