EXPERIMENTAL DETERMINATION OF THE KINETIC CONVERSION RATE OF GASEOUS TRITIUM INTO HTO

To assess the impact of atmospheric tritium releases from a fusion plant to the environment, the dose to man usually is determined under the conservative assumption that all tritium is released in the more dangerous oxide form. Under accidental conditions, however, where tritium could be released predominantely in gaseous form from a stack, this assumption leads to a considerable overprediction of the hazard.
