“…There are studies which demonstrate that tritium activity from the free water of the vegetation samples usually reflects the tritium from the environment while tritium from the organic fraction is usually higher that the regional ambient HTO (Masakazu Ota et. al, 2017;Kimura et. al., 1998).…”

Also, the evaluation of the aqueous component of the wine or other alcoholic beverages (Kimura et. al., 1998;LLNL, 2016) represents an important part in the process of dose calculation and can provide information about the presence and movement of tritium release to the environment.…”

Tritium measurement from aqueous fraction of the wines of known vineyard can be a useful tool in reconstruction of the tritium activity in different areas and makes possible to date the time of the harvest of the grapes. The goal of this study was to develop a suitable method for purification of the aqueous phase from the wine samples, obtained from different type of wines, in order to determine tritium activity concentration using liquid scintillation counting. In this work the influence of the purification method applied to the aqueous samples resulted from wine distillation was assessed by deuterium and tritium measurements, content of organic carbon, pH and conductivity. The most reliable purification method used for wine aqueous fractions, according with the results obtained for pH, and total organic carbon content is chemical treatment followed by lyophilization.
