FIELD: medical equipment; radiation therapy.
SUBSTANCE: radioactive source has radioisotope disposed inside air-tight biocompatible container. At least some part of container is made profiled and have rough, non-smooth surface. Radioactive source is made by loading it inside air-tight container. Composition has assemblage of radioactive sources mounted in line onto biologically decomposed material. Invention helps to improve ultrasonic visibility of source and/or reduce the trend of source to migrate in patient's body after implantation.
EFFECT: improved quality of treatment.
