The effect of various diluent gases on the rate of the self-induced exchange between tritium and water vapor was investigated. The gases studied were helium, neon, argon, krypton, xenon, air, nitrogen, oxygen, hydrogen, and ammonia. The average value found for a second-order rate constant, for inert gases agreed with that found previously See AD-246 259. Air and nitrogen as diluents yielded rate constants of 0.00127 and 0.00086 mlmchr, respectively. Oxygen increased the rate over that observed in air, and hydrogen and ammonia both were found to decrease it sharply. Author
