Organically Bound Tritium in the Environment: First Investigation of Environmental Survey in the Vicinity of a French Research Centre

A follow up of the decrease of non exchangeable organically bound tritium levels in the surroundings of a nuclear research center

“…In addition, several papers also deal with modelling either to compare observed and predicted values (Davis et al, 2005;Keum et al, 2006;Ota et al, 2007) or for tritium dose estimates (DeVol and Powell, 2004;Hisamatsu et al, 1987;König, 1990). Taking advantage of tritium releases, several studies have investigated tritium distribution in various environmental samples to determine Tissue Free Water Tritium (TFWT) and NE-OBT activities and also the conversion factors (Vichot et al, 2008). In this study our objective is to monitor NE-OBT concentrations around a nuclear research centre where only minute tritium releases occur.…”

“…Des campagnes annuelles de mesures du tritium incorporé dans la matière organique des végétaux sont également réalisées. Des études à caractère scientifique sont par ailleurs régulièrement menées (Vichot et al, 2007 ;Vichot et al, 2008 ;Boyer, 2009 ;Boyer et al, 2009aBoyer et al, , 2009b.…”
