In a 62Ni(d,p)63Ni reaction, the 63Ni will beta- decay to 63Cu.  The proton
will have ~ 5 MeV and will excite 11 keV electrons, which can easily be
shielded.  There will be a delayed gamma emission after the beta- decay of
Q=87 keV, however, which will not be fully shielded even by 1cm of lead.
 If there is vigorous deuteron stripping, there will be a lot of motivation
to remove 62Ni from the nickel.
