✦ Synopsis
Various quantities of anthropogenic 129 I have been released out worldwide in the last decades, principally by nuclear reprocessing plants in England and France. This work was a preliminary attempt to exploit the spatial and temporal variability of these emissions to investigate the possibility of tracing the provenance and age of wines worldwide. Using carrier free iodine extraction followed by measurements by Accelerator Mass Spectrometry (AMS) at the Tandetron of Gif-sur-Yvette, we find a good correlation between the distribution of 129 I/ 127 I and the extent to which 129 I releases are expected as a function of the geographical setting. 129 I concentrations, also measured in wines using the same method but with a carrier, show the same pattern.
