Medical-grade Cobalt-60

Medical-grade Cobalt-60, referred to as High Specific Activity (HSA) Cobalt-60 in the healthcare industry, has great benefit to human health across the globe.

Nordion is the world’s leading supplier of medical-grade Cobalt-60 sources for radiation therapy. This source model is double encapsulated and delivers the industry standard in performance, reliability, and service in radiation therapy.

High Specific Activity Cobalt-60 for Cancer Treatment

Produced in power reactors throughout the world, Cobalt-60 emits high energy gamma rays used in the treatment of cancers. HSA Cobalt-60 is at the forefront of innovative new medical technologies.

Cobalt-60 therapy allows doctors to deliver higher doses of radiation to tumors with limited damage to the surrounding healthy tissue and/or organs. For many cancers, Cobalt-60 therapy is one of the most precise and advanced forms of radiation treatment available*.

Stereotactic radiosurgery (SRS) is a special form of radiation therapy—it’s a non-invasive form of surgery. Stereotactic radiosurgery allows precisely focused, high dose x-ray or gamma beams to be delivered to a small, localized area of the brain. It is used to treat small brain and spinal column and spinal cord tumors (both benign and malignant)*.
