What is the product of decay for decay of cobalt-60?
What is the product of decay for decay of cobalt-60?
Nickel-60
Cobalt-60 decays to Nickel-60 plus an electron and an electron antineutrino. The decay is initially to a nuclear excited state of Nickel-60 from which it emits either one or two gamma ray photons to reach the ground state of the Nickel isotope.
How does cobalt-60 decay to nickel-60?
Cobalt-60 decays, with a half-life of 5.3 years, to the element nickel-60 by the emission of a 0.32 MeV beta particle.
What is the electron configuration for cobalt-60?
Cobalt-60 (Co-60 or 60Co) is a radioactive metal that is used in radiotherapy. It produces two gamma rays with energies of 1.17 MeV and 1.33 MeV….

What is the use of CO-60 isotope?
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.
How do you make a cobalt-60?
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.
How Cobalt 60 is produced?
What is the use of CO 60 isotope?
How many protons neutrons and electrons does Cobalt 60 have?
The number of Cobalt 60 protons neutrons electrons are 27,33, and 27 respectively.

What type of radiation is Co 60?
Gamma Rays
Type of Radiation Emitted: Beta Particles. Gamma Rays.
Why is cobalt-60 commonly used in radiation therapy?
Cobalt-60 (60Co) and caesium-137 (137Cs) are the most widely used sources of gamma radiation. Co produces gamma rays with energies of 1.173 and 1.332 MeV and has a half-life of 5.27 years, whereas 137Cs produces gamma rays with an energy of 0.662 MeV and has a longer half-life of 30.1 years.
How much does Cobalt-57 decay by electron capture?
1 Decay Scheme. Co-57 decays 100% by electron capture to the excited levels of 706.42 keV (0.183%) and 136.47 keV (99.80%) in Fe-57. Le cobalt-57 se dsintgre par capture lectronique vers des niveaux excits du fer-57. 2 Nuclear Data.
What is the decay of co 60m?
Co 60m can also decay by emission (with an energy of 1.550 MeV) to an excited state of Ni 60. The small branching ratio is indicated by a small blue triangle in the bottom right corner of nuclide box. The excited state decays further to the ground state through the emission of 1332 keV gamma photon.
What is the most important gamma emission on the decay scheme?
On the decay scheme can be seen that the most important (0.606 MeV) emmision is followed by two different gamma emission at level 364 keV. One with 364 keV and one with 284 keV.
What is electron capture decay?
Electron capture is the predominant mode of decay for neutron deficient nuclei whose atomic number is greater than 80. The two processes compete to differing degrees for the nuclei between atomic numbers 30 and 80.
