Abstract
An apparatus includes a support, including an outer surface and configured for insertion into a body of a subject. The apparatus further includes multiple atoms of a radionuclide, which radioactively decays to produce a daughter radionuclide, coupled to the outer surface, and a layer of a polymer, which covers the atoms so as to protect the atoms from being washed away, yet allows diffusion of the daughter radionuclide through the layer. Other embodiments are also described.
