- Abstract
- The electrolysis conditions in a proton exchange membrane (PEM) cell were optimized by varying the current supplied; the detection efficiency for gaseous tritium generated from the PEM cell under optimized electrolysis conditions was analyzed. The current was optimized to 7A. Under the optimized current condition, the change in activity of the tritiated water before and after electrolysis was 200 ± 11kBq. When tritiated water with tritium activity concentration of 2912kBq/L was electrolyzed, the detection efficiency was 31.3 ± 1.3%. Moreover, the minimum detectable activity of gaseous tritium was 10.3 ± 0.8kBq/m3 in 5min.
