An integral source material having at least one nuclide that is activatable by exposure to radiation, the nuclide is a chemically bound constituent of a polymer of the integral source material, wherein the integral source material is configured before activation to provide a device. A radioactive stent comprising a generally cylindrical thin-walled structure, the stent including a base matrix polymer having at least one nuclide as a chemically bound constituent thereof, the nuclide capable of being activated by exposure to radiation. And a radition-emitting brachytherapy device comprising a seed, wherein the seed is formed from a base polymer matrix having a nuclide as a chemical constituent, the nuclide activatable by exposure to ionizing radiation. And a method of inhibiting stenosis or restenosis at a vessel wall of a patient.
