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.
