Abstract:
A radiation delivery device, which comprises:a substantially non-conductive, flexible substrate selected from the group consisting of flexible fiber and flexible film formed from a radiation compatible material and which is sufficiently flexible to deform under its own weight, and a sufficient amount of radioactive palladium-103 bonded to the outer surface of the substrate to provide an apparent activity of the radiation delivery device, as measured adjacent to the surface of the substrate, of from about 0.5 &mgr;Ci to about 300 Ci/device, and wherein the radioactive palladium-103 comprises palladium-103 fabricated in a particle accelerator and said palladium-103 forms at least a substantial portion of the outer surface of the radiation delivery device such that the radioactive palladium-103 can be positioned closely adjacent to, or in direct contact with, a location to be treated with radiation.
