The cobalt-60 isotope undergoes beta decay with a half-life of 5.272 years. 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 cobalt-60 is produced?
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 many isotopes does cobalt have?
There are 30 isotopes and isomers of cobalt that are recognized.What is the most common isotope of cobalt?
Most common isotopes: Co-59 (100 percent natural abundance)
How do you write cobalt 60?of cobalt is cobalt-60 (Co-60). Cobalt-60 is a byproduct of nuclear reactor operations. It is formed when metal structures, such as steel rods, are exposed to neutron radiation.
Article first time published onWhich isotope is produced when 216po decays by emitting an alpha particle followed by 2 beta particles?
17. Which isotope is produced when 216Po decays by emitting an alpha particle followed by 2 beta particles? Po –> α particle + 2β particles + ? Cobalt-56 decays by emitting a positron.
How is Caesium 137 produced?
Cesium-137 is produced by nuclear fission. Fissioning that occurs without any outside cause is called “spontaneous fission.” for use in medical devices and gauges. It is also one of the byproducts of nuclear fission processes in nuclear reactors and nuclear weapons testing.
Which radioactive isotope is used in geological dating?
Uranium–lead dating method Uranium–lead radiometric dating involves using uranium-235 or uranium-238 to date a substance’s absolute age. This scheme has been refined to the point that the error margin in dates of rocks can be as low as less than two million years in two-and-a-half billion years.
What nucleus decayed when americium 241 and beta particle were produced?
The first decay product of americium-241 is neptunium-237, which also decays and forms other daughter elements. The decay process continues until stable bismuth is formed. The radiation from the decay of americium-241 and its daughters is in the form of alpha particles, beta particles, and gamma rays.

Which isotope decays by positron emission?
Cobalt-56 decays by emitting a positron.
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.
What is a Cobalt-60 machine?
The machine is intended to deliver precise radiation treatment to the patient suffering from a cancerous growth. Cobalt-60 therapy can be used anywhere on the body but is particularly useful in brain tumour patients because of its preciseness. There are two types of sources that are used for radiation therapy.
What products use cobalt?
Cobalt is also used to make airbags in automobiles; catalysts for the petroleum and chemical industries; cemented carbides (also called hardmetals) and diamond tools; corrosion- and wear-resistant alloys; drying agents for paints, varnishes, and inks; dyes and pigments; ground coats for porcelain enamels; high-speed …
What is the parent isotope of the daughter isotope nickel-60?
Ni has been used to date the terrestrial age of meteorites and to determine abundances of extraterrestrial dust in ice and sediment. Nickel-60 is the daughter product of the extinct radionuclide 60Fe (half-life = 1.5 Myr).
How is cobalt 57 produced?
Radioactive isotopes can be produced by various nuclear reactions. For example, the isotope 57Co is produced by cyclotron irradiation of iron. The principal reaction involved is the (d,n) reaction 56Fe + 2H → n + 57Co.
What is AM 241 used for?
Americium-241 is used as a neutron source in non-destructive testing of machinery and equipment, and as a thickness gauge in the glass industry. However, its most common application is as an ionization source in smoke detectors, and most of the several kilograms of americium made each year are used in this way.
How is cobalt produced?
Most cobalt is formed as a by-product of nickel refining. A huge reserve of several transition metals (including cobalt) can be found in strange nodules on the floors of the deepest oceans. The nodules are manganese minerals that take millions of years to form, and together they contain many tonnes of cobalt.
What compounds is cobalt found in?
These compounds compounds include: cobalt oxide, cobalt potassium nitrite, cobalt aluminate, and cobalt ammonium phosphate. Cobalt compounds can also be used as catalyst.
How many neutrons does Cobalt-60 have?
Cobalt-60 has 27 protons (thus 33 neutrons).
What is the isotopic symbol for cobalt?
Cobalt is a chemical element with symbol Co and atomic number 27.
What is the isotope notation for carbon 14?

How is cobalt-60 administered?
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 isotope remains after the alpha decay of polonium 212?
Explanation: Polonium-212 undergoes alpha decay to produce lead-208, which means that it gives off alpha radiation, i.e. alpha particles.
What is alpha decay and beta decay?
Alpha decay – A common mode of radioactive decay in which a nucleus emits an alpha particle (a helium-4 nucleus). Beta decay – A common mode of radioactive decay in which a nucleus emits beta particles. The daughter nucleus will have a higher atomic number than the original nucleus.
Which type of energy does alpha decay generate?
Alpha particles have a typical kinetic energy of 5 MeV (or ≈ 0.13% of their total energy, 110 TJ/kg) and have a speed of about 15,000,000 m/s, or 5% of the speed of light. There is surprisingly small variation around this energy, due to the heavy dependence of the half-life of this process on the energy produced.
