1. A target insert for the production of Ac-225 in a particle accelerator comprising:
a metal body comprising:
a central flat area for deposition of Ra-226;
a channel surrounding the perimeter of the central flat area;
a hollow section opposite the central flat area; and
an area of Ra-226 disposed on the central flat area;
a protective layer disposed atop the area of Ra-226 and conforming to the metal body such that the protective layer is also disposed onto the channel surrounding the perimeter of the central flat area;
and a crimp ring disposed on top of the protective layer in the channel surrounding the perimeter of the central flat area, wherein the crimp ring has been compressed to fill the channel and attach and seal the protective layer to the metal body by deformation of the crimp ring as a result of said compression, wherein the protective layer is attached and sealed to the metal body by the crimp ring alone.
