Tritium is preferentially absorbed into nickel. Most of it would be retained in the nickel powder, if it were present.
From: Jed Rothwell . . . a signal should show up above background on his meter - especially when the Rossi device is disassembled, as it is in the Penon report. They disassemble it by cutting it in half with a saw, don't they? There is no way you could capture tritium by this method! - Jed
