Abstract
Radioactive sources, preferably radioactive seeds, for use in brachytherapy comprising a radioisotope within a sealed biocompatible container, wherein at least one part of a surface of the container is roughened, shaped or otherwise treated so that it is no longer smooth. The surface treatment may enhance the ultrasound visibility of the source and/or reduce the tendency of the source to migrate once implanted in a patient's body. Preferred radioisotopes are palladium-103 and iodine-125.
