The XRD analysis was performed to verify the identity of the as-supplied bulk samples and check for other phases. The data were generated on the 5th of June 2014 at the Department of Earth Sciences, University of Cambridge, Cambridge, UK. A bulk sample of the as-supplied CeO2 was powdered using mortar and pestle and analysed on a D8 Bruker diffractometer equipped with a primary Ge monochromator for Cu Ka1 and a Sol-X solid state detector operating in standard Bragg-Brentano geometry. The sample was spun during signal collection and a zero-background sample holder was used.

The EPMA analysis was performed to check the composition of the as-supplied bulk samples. The data were generated on the 3rd of July 2014 at the Department of Earth Sciences, University of Cambridge, Cambridge, UK. Prior to the analysis, the samples were embedded in a resin, polished and carbon coated to ensure conductivity for the analysis using a Cameca SX-100 electron microprobe analyser. Calibration of the equipment was performed using a set of rare earth elements.

The ICP-MS analysis was performed to measure 140Ce concentration in the extracted solutions. The data were generated on the 23rd of July 2014 at the Department of Earth Sciences, University of Cambridge, Cambridge, UK, on a Perkin Elmer SCIEX Elan DRC II quadrupole ICP-MS.

The data can be accessed through the University of Cambridge Data Repository.
