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 … See more Before the development of medical linear accelerators in the 1970s, the only artificial radiation source used for teletherapy was the x-ray tube. Researchers found ordinary x-ray tubes, which used voltages of 50-150 keV, could … See more The role of the cobalt unit has partly been replaced by the linear accelerator, which can generate higher-energy radiation, and does not produce the See more • Gamma knife See more As used in radiotherapy, cobalt units produce stable, dichromatic beams of 1.17 and 1.33 MeV, resulting in an average beam energy of 1.25 MeV. Cobalt-60 has a half-life of 5.2713 years. See more • public domain image of cobalt machine See more WebFeb 1, 2024 · Physical Characteristics. Cobalt-60 machines and linacs both are capable of providing teletherapy. Teletherapy is the dominant form of radiotherapy, with typically 86–96% [5] of radiotherapy carried out by teletherapy in LMICs and the remainder by brachytherapy (excluding the area of radionuclide therapy with unsealed sources). The …

Webnique is teletherapy (or beam therapy) in which the source of radiation remains outside the body and the beam of radiation is directed at the tumor through the overlying tissue. The source of radiation may be an X-ray tube, a "supervoltage" machine such as a betatron or a linear accelerator, or a radioisotope which emits high energy gamma-rays.
