As I remember from his papers, he actually tested in some tunnels to improve his neutron detection S/N. What he found was that the neutrons were always undetectable in his system, but the tritium measurement was 10 sigma confident. It set a limit to how many orders of magnitude the neutron branch of his reaction must be below the tritium branch - something like at least E6 below the tritium branch.
I have not seen him reporting transmutation of the host metal - perhaps it is only catalytic. I do remember seeing what Jones said about having switched to mu-metal and seeing a boost in tritium production. Other than this host metal and its internal purity, I think his gasses are highly pure (five 9s).
