⚕ Why is cobalt 60 used in a treatment of cancer?

  • Cobalt therapy or cobalt-60 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.

In addition to its applications in radiation processing, Cobalt-60 is used as a radiation source for medical radiotherapy where it is used in cancer treatment to control or kill malignant cells. Cobalt-60 is used as the radiation source in Gamma Knife equipment that enables non-surgical treatment of brain tumours.

Cobalt-60 is used in the inspection of materials to reveal internal structure, flaws, or foreign objects and in the sterilization of food. In medicine, it is used to treat cancer and to sterilize medical equipment.

Cobalt-60: the heart of gamma-radiation sterilization. Currently, more than three million cubic metres of single-use medical devices are sterilized by gamma radiation each year. The wide use of this method of sterilization is a result of the lethal effects of ionizing radiation on microbial populations and the penetrative powers of cobalt-60.

In medicine 60 Co is used as a radiotracer isotope, sterilisation for surgical equipment and most commonly, as a radiation source for radiotherapy. 60 Co had been used in treating malignancies for many decades.

Cobalt-60 units supply gamma radiation of two monochromatic wavelengths (1.17 and 1.33 mev), and the soft beta radiation is easily filtered out by approximately 0.16 mm of steel. Such units therefore have made possible the world-wide use of the equivalent of supervoltage roentgentherapy.

In medicine, cobalt-60 destroys cancerous cells and is used in the sterilisation of medical equipment. However there are some problems associated with cobalt-60. Cobalt 60's 5.24 years half-life offers disadvantages, for example cobalt-60 pencils require frequent replenishment at a substantial cost due to the extensive time spent in the reactor.

Cobalt-60. Cobalt-60 (60Co) has been used for radiotherapy cancer treatment, food irradiation and industrial applications. As cobalt-60 decays into a stable nickel-60 isotope, two wavelengths of high-energy gamma-rays are emitted (1.17 and 1.33 MeV- average of 1.25 MeV used).

Cobalt emits high-energy gamma rays and is the most frequently used radioisotope in radiotherapy. Cobalt-60 is also used in blast furnaces to determine times and to quantify income to measure the furnace performance. It is also is specifically made for use in gamma irradiation plants – it is not a waste product of nuclear power plants.

Cobalt-60 (60 Co) is a synthetic radioactive isotope of cobalt with a half-life of 5.2713 years. It is produced artificially in nuclear reactors.Deliberate industrial production depends on neutron activation of bulk samples of the monoisotopic and mononuclidic cobalt isotope 59 Co. Measurable quantities are also produced as a by-product of typical nuclear power plant operation and may be ...
