It would be, but here on Earth increasing the gravity enough to make a noti=
ceable difference is not really an option.

On the other hand, there is another way to do it which is quite commonly us=
ed, especially for isotopes with really short halflives. Once made, you put=
 them in a particle accelerator (like a cyclotron) and keep them moving at =
almost the speed of light. That slows down time for the particles and keeps=
 then around long enough for them to be beamed from the cyclotron when need=
ed.  At 99.5% the speed of light, time slows down by a factor of 10.

  Is the rate of radioactive decay (half life) affected by gravity; slower =
as gravity increases ?
