Working Group on Modelling of tritium and carbon-14 transfer to biota and man

Website: http://www-ns.iaea.org/projects/emras/emras-tritium-wg.htm

The Working Group focuses on improving models of OBT formation and translocation in plants, animals and fish. The Working Group will necessarily have to consider HTO as well, since an understanding of environmental HTO is needed before OBT can be modelled. Carbon-14 will also be on the agenda since the dynamics of carbon and OBT are very similar.
