Within the IAEA program EMRAS, an analysis of the consequences of an acute atmospheric release of tritium (10g) is performed. This study aims at giving practical guidance to decision-makers in the case of severe release depending on the circumstances of the accident and will be useful for authorities to reduce, if necessary, the consequences of such a release.

Our analysis establishes a classification of different pathways; defines the importance of the different parameters; assists in the definition of a post-release monitoring and emergency plan; and gives an evaluation of what is required to return to a normal situation.

The difference between the various chemical forms of tritium is addressed.
