“…Comme dans des travaux précédents (Barry et al, 1999 ;Galleriu et al, 1995), la distribution des résultats varie selon les scénarios et les modèles utilisés. Les différences pour les cas de pluie et de nuit atteignent un facteur 10 ; ceci est dû en partie aux modèles de dispersion atmosphériques mais surtout à la modélisation des transferts aux aliments.…”

RÉSUMÉWithin the framework of a seminar on environmental and health impact of tritium organized by article 31 Euratom expert group in November 2007, it was expected to make a point on tritium knowledge and to define R&D and regulatory axes. This document presents the different sources of tritium, different methods of measurement associated to tritium processes and survey, transfer in the biosphere compartments in normal and accidental conditions. It suggests some R&D subjects and discusses some regulatory aspects.

“…Several numerical models of tritium transfer in the environment were developed (Barry et al, 1999;Belot et al, 2005). However, it has been difficult to describe the HT deposition process quantitatively in a model because there are many controlling factors on the atmospheric HT deposition to soil.…”

“…Many authors have presented studies and reviews on exchanges between two compartments (Guenot and Belot, 1984;Garland and Ameen, 1979;Boyer et al, 2009;Melintescu, 2011;Patryl et al, 2011). Many papers present intercomparisons of model predictions (Barry et al, 1999), with experimental work in terms of concentration (see the IAEA programmes: BIOMOVS, BIOMASS (IAEA, 2003), EMRAS I (IAEA, 2012) & II). In the framework of the EMRAS programme, an integrated approach has been developed , and the present work deals with the key mechanisms and concepts for understanding tritium transfers from air to man, considering all pathways.…”

During an accidental release of tritium, mechanisms of hydrogen transfer from air to man are very numerous, dependent on multiple climate, physiological and biological parameters, and the kinetic is highly variable from one environmental compartment to another. To evaluate the impact of an acute tritium release requires either an overall assessment of the state of the environment during the release and the following hours from a number of restricted data, or the establishment of a significant data bank, a complex model and a system of data acquisition in real time whose potential for daily purposes is very hypothetical. To facilitate the first approach, this paper discusses the key elements of the mechanisms to guide the choice of parameters for a rapid assessment of the situation, and to clarify the types of measurements to carry out and their interpretation.
