Given that tritium is expensive, toxic, and tightly controlled and that there is no requirement for a gas
- and given that you are interested in Mills work and that potassium is a BLP catalyst, and that 40K is mildly radioactive and available in enriched form and has a low melting point. Get hold of a potassium-40 isotope enriched sample, GM meters with datalogging - some Raney Nickel, and measure the counts before and after impregnating the sample into the Raney Nickel using heat and vacuum and exercising due caution. Best to datalog both measurement over several days or even weeks. -----Original Message----- From: Frank Roarty How about circulating a radioactive gas through fine metal powder, assuming it doesn't become pyrophoric it would create through channel cavities between the grains instead of dead end cavities inside the metal. -----Original Message----- From: Stephen A.

How about, forget the "massive" bit, just substitute tritium oxide for deuterium oxide and load any-old-material with Casimir sized pores with it, and see if the decay rate drops. Dunno if it would be sensitive enough, but in principle it seems like it would be simple and clear evidence one way or the other.
