With respect to inhalation doses the reemission of HTO from the area source established in soil after HT releases is the most important process. In two field experiments performed in France and Canada reemission was studied by successive evaluations of tritium contents in soil and corresponding air samples. It was found that the reemission rate is essentially dependent upon the specific activities in air and soil. Evaporation conditions support reemission, while dew formation and rainfall as well as HTO diffusion into deeper soil layers have the opposite effect. Dose consequences of a HT release were evaluated from time-integrated tritium concentrations in air and breathing rates as well as by analyses of urine samples of the experimenter.
