Cobalt-60 (60 Co) is a synthetic radioactive isotope of cobalt with a half-life of 5.2714 years. [3][4]: 39 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. . [5] .

Cobalt-60, radioactive isotope of cobalt used in industry and medicine. Cobalt-60 is the longest-lived radioactive isotope of cobalt, with a half-life of 5.27 years. It is produced by irradiating the stable isotope cobalt-59 with neutrons in a nuclear reactor.

Co-60 is used medically for radiation therapy as implants and as an external source of radiation exposure. It is used industrially in leveling gauges and to x-ray welding seams and other structural elements to detect flaws. Co-60 also is used for food irradiation, a sterilization process.

2025年2月6日 · Cobalt (chemical symbol Co) is a hard, gray-blue metal that is solid under normal conditions. The most common radioactive isotope of cobalt is cobalt-60 (Co-60).

What is cobalt-60? The most common radioactive form of cobalt is cobalt-60. It is produced commercially and used as a tracer and radiotherapeutic agent. It is produced in a process called activation, when materials in reactors, such as steel, are exposed to neutron radiation. What are the uses of cobalt-60? Cobalt-60 is widely used as a medical and

Cobalt-60 (60 Co) is a synthetic radioisotope that has been used in both external beam radiation therapy and brachytherapy. 60 Co decays via \(\beta\) decay to an excited state of Nickel-60 which then emits two high energy (1.17MeV and 1.33MeV) gamma-rays.

Direct parent isotope is: 60 Fe. Nuclear isomers or excited states with the activation energy in keV related to the ground state. The following table shows the atomic nuclei that are isotonic (same neutron number N = 33) and isobaric (same nucleon number A = 60) with Cobalt-60.

2021年10月14日 · Cobalt-60, 60 Co, is a synthetic radioactive isotope of cobalt with a half-life of 5.2714 years. It is produced artificially by neutron activation of the isotope 59 Co. 60 Co decays by beta decay to the stable isotope nickel-60 (60 Ni). Cobalt is …

Cobalt-60 is artificially produced by bombarding a target material, either cobalt-59 or nickel-60, with neutrons. This reaction is produced by nuclear weapons detonations and in nuclear reactors. IS COBALT-60 HAZARDOUS? Cobalt-60 emits two high energy gamma rays, making cobalt-60 both an internal and external hazard.

Cobalt 60 radiation is a radioactive isotope primarily utilized in radiation therapy for various types of cancer, including breast, bladder, oral, and brain cancers. The primary purpose of using Cobalt 60 is to shrink or destroy tumors, as well as to eliminate any residual cancer cells following surgical procedures.
