Figure 7
Tomographic reconstructions of a pitchblende stone (an ore containing essentially U3O8) showing that uranium is not uniformly spread and neglects entire zones inside the sample. (a) Photograph of the stone in its aluminium support as it was scanned at the ESRF beamline. (b)–(e) Four slices through the sample taken at different heights. The size of each slice is 12 × 12 × 0.1 mm3. |
