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.
The main uses for 60 Co are: As a tracer for cobalt in chemical reactions; Sterilization of medical equipment. [8] Radiation source for medical radiotherapy. [9] Cobalt therapy, using beams of gamma rays from 60 Co teletherapy machines to treat cancer. Radiation source for industrial radiography. [9] Radiation source for leveling devices and ...
Cobalt-60 (60 Co) is useful as a gamma ray source because it can be produced in predictable quantities, and for its high radioactivity simply by exposing natural cobalt to neutrons in a reactor. [8] The uses for industrial cobalt include: Sterilization of medical supplies and medical waste
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.
Cobalt-60 beam machine from 1951. Cobalt units use radiation from cobalt-60, which emits two gamma rays at energies of 1.17 and 1.33 MeV, a dichromatic beam with an average energy of 1.25 MeV. The role of the cobalt unit has largely been replaced by the linear accelerator, which can generate higher energy radiation.
Cancer recovery coach Michelle Patidar of Chicago shared the items in her kitchen that she's replaced with safer options after being diagnosed with cancer at 32 years old.
The headquarters are the main manufacturing facilities for medical isotopes, used in medical imaging and radiopharmaceuticals, and for cobalt-60 sources and industrial food irradiators. The Nordion Gamma Centre of Excellence (GCE) is a gamma irradiation research, training, and demonstration facility located in Laval, Quebec, Canada.
