Molecular tritium contribution to the doses by ingestion and re-emission from releases in inertial fusion reactors

The evaluation of the radiological environmental impact of molecular tritium emission to the atmosphere on inertial fusion reactors (IFE) have different phases. The factors influencing the primary phase (atmospheric releases) are boundary conditions such as atmospheric and geometric grid from the emission point. The second phase occurs when the tritium is deposited in the ground, and it suffers the transformation rapidly to tritiated water vapour (less than 1 week). This process depends on the kind of soils (clay, loam or sand), relative humidity and microporosity of soil. This phase is decisive in the dosimetric effects by molecular tritium and in the chronic and collective doses to population
