The paper I uploaded the other day says: "[All] these three cells, which were sampled and counted periodically, have displayed a characteristic oscillatory variation of the tritium activity. While an in-crease in tritium level can be understood as a production phase, the decreasing phase, lasting from 5 to 10 days (in one case up to 20 days), is difficult to understand. A close scrutiny of our sampling, distilling, and counting techniques confirms that the decrease in tritium level is genuine and not attributable to any artifact."
http://lenr-canr.org/acrobat/Sankaranarinvestigatb.pdf See Figs. 1, 2 and 3. Would anyone like to hazard a guess as to why the tritium goes away? That being consumed by a secondary reaction? Absorbed by something? I doubt it is leaking out. - Jed
