Cobalt therapy is the medical use of gamma rays from the radioisotope cobalt-60 to treat conditions such as cancer.Beginning in the 1950s, cobalt-60 was widely used in external beam radiotherapy (teletherapy) machines, which produced a beam of gamma rays which was directed into the patient's body to kill tumor tissue.
External beam radiation therapy (EBRT) is a form of radiotherapy that utilizes a high-energy collimated beam of ionizing radiation, from a source outside the body, to target and kill cancer cells. The radiotherapy beam is composed of particles, which are focussed in a particular direction of travel using collimators [ 1 ] .
In addition to their uses in radiography, both cobalt-60 (60 Co) and iridium-192 (192 Ir) are used in the radiotherapy of cancer. Cobalt-60 tends to be used in teletherapy units as a higher photon energy alternative to caesium-137, while iridium-192 tends to be used in a different mode of therapy, internal radiotherapy or brachytherapy.
Radiosurgery is surgery using radiation, [1] that is, the destruction of precisely selected areas of tissue using ionizing radiation rather than excision with a blade. Like other forms of radiation therapy (also called radiotherapy), it is usually used to treat cancer.
Between 1958 and 1972, the Riverside Methodist Hospital in Columbus, Ohio became the first hospital in Central Ohio to develop an extensive cobalt therapy program, where the use of cobalt-60 became the dominant radiation source for treating patients with cancer. In 1973, 30-year-old Joel Axt was hired by the hospital as the resident physicist ...

Radioimmunotherapy (RIT) uses an antibody labeled with a radionuclide to deliver cytotoxic radiation to a target cell. [1] It is a form of unsealed source radiotherapy.In cancer therapy, an antibody with specificity for a tumor-associated antigen is used to deliver a lethal dose of radiation to the tumor cells.
Nordion Inc., a Sotera Health company, is a health science company that provides Cobalt-60 used for sterilization and treatment of disease (radiotherapy). Nordion is headquartered in Ottawa, Ontario, Canada, with facilities in Vancouver, British Columbia and Laval, Quebec. Riaz Bandali is the company's President.
