The authors describe the conversion reaction of tritium gas (T/sub 2/) to tritiated water studies experimentally at initial tritium concentrations between 9.6 x 10/sup -3/ and 48 GBq . m/sup -3/ (2.6 x 10/sup -4/ and 1.3 Ci . m/sup -3/) in air. Effects of water vapor and catalysts on the conversion reaction were also examined. Stainless steel, copper, paint, and platinum black were used as potential catalytic surfaces. First-order rate constants for the reaction in air are found to be independent of initial tritum concentration, and there is no effect from water vapor on the reaction. The conversion is insensitive to the presence or absence of stainless steel and copper.
