Conversion rates of tritium gas (T/sub 2/) to tritiated water are reported for tritium in ambient air and in nitrogen mixtures for initial tritium concentrations between 10/sup -3/ and 1 Ci/m/sup 3/. Evidence suggests that, for air mixtures, production of condensable species, primarily HTO, occurs at a rate commensurate with the tritium decay rate. Nitrogen with less than 0.05% oxygen decreases this rate by a small (about 25%) amount. Irradiation with up to 10 Krad /sup 60/Co does not measurably affect the conversion rate in ambient air. This new data, along with the data from other authors, reveals that over the range of 10/sup -3/ to 10/sup 6/ Ci/m/sup 3/, there are three reaction order regimes: (1) first order between 10/sup -3/ and 10 Ci/m/sup 3/, (2) approximately second order between 10 and 10/sup 4/ Ci/m/sup 3/, and (3) first order above 10/sup 4/ Ci/m/sup 3/.
