Is cobalt used to treat cancer?
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.
What are the side effects of cobalt poisoning?
Radiation therapy, sometimes called radiotherapy, x-ray therapy radiation treatment, cobalt therapy, electron beam therapy, or irradiation uses high energy, penetrating waves or particles such as x rays, gamma rays, proton rays, or neutron rays to destroy cancercells or keep them from reproducing.

Does radiation shorten your life?
"Rapidly dividing cells, such as cancer cells, are more affected by radiation therapy than normal cells. The body may respond to this damage with fibrosis or scarring, though this is generally a mild process and typically does not cause any long-term problems that substantially affect quality of life."
Do cancer survivors live long?
Many people live much longer than 5 years after their cancer diagnosis. The term does not mean a person will only survive for 5 years. For example, 90% of people with breast cancer will be alive 5 years after the diagnosis of cancer.Apr 9, 2021

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. The cobalt-60 isotope has a half-life of 5.3 years so the cobalt-60 needs to be replaced occasionally.
How many volts are needed for a MeV xray?
To produce a significant amount of MeV x-rays required potentials on the tube of 3-5 million volts (3-5 megavolts), necessitating huge, expensive x-ray machines. By the late 1930s these were being built, but they were available at only a few hospitals.
What was the only radiation source used for teletherapy?
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 treat superficial tumors, but did not have the energy to reach tumors deep in the body.
