Isoray is a medical equipment manufacturer headquartered in Richland, Washington, focusing on Cesium-131 brachytherapy seeds used to treat cancer. The radioactive seeds are sealed in titanium capsules and implanted directly into the tumor, for example in the prostate, to provide targeted radiation therapy. The unique properties of Cesium-131 are linked with potential clinical benefits for patients receiving seed brachytherapy. Founded in 1998 to produce and commercialize Cesium-131 seeds, Isoray serves major medical centers, hospitals, and clinics across the United States. The company operates with a relatively small workforce within the medical device sector.
