Recent work has not changed these values. A factor of ten in this wide range probably results from error while most of the range is produced by unknown factors involving the different chemical environments and methods used.
Several studies report results in sufficient detail to eliminate most objections.
Bockris et al. O. Tritium production was monitored by periodic sampling. A similar, nonactive cell was run at the same time in the same room. Figure 4 shows how the tritium concentration changed with time at three different cell currents. A great deal of turbulence would stop tritium production which could be restarted by applying various initiating techniques.
