Abstract
Comparison of the minimum detectable amount of tritium by different counting devices shows that proportional gas counting is the most sensitive method at the present time. A new method of tritium proportional gas counting using propane as counting gas is described. The propane is formed by hydrogenation of propyne with palladium oxide as a catalyst. Using a 2.5‐liter counter filled with propane at 2.2 atm pressure requires a sample size of half a mole of H2O or H2. For a background of 5.3 cpm, this results in a minimum detectable concentration, without isotopic enrichment of tritium, of 3 TU equal to ±2σ for a counting time of 1000 min.Keywords
