What is cobalt-60 decay equation?
Cobalt-60 is a nuclide that β− decays in the following manner: 60Co → 60Ni + β−+ neutrino. The neutrino is a particle emitted in beta decay that was unanticipated and is of fundamental importance.
What decay does cobalt-60 undergo?
Cobalt-60 decays by beta and gamma emission to non-radioactive nickel. Most of the radiation from the decay of cobalt- 60 is in the form of gamma emissions; some is in the form of beta particles. Beta particles are generally absorbed in the skin and do not pass through the entire body.
What is the decay constant for the radioactive disintegration of cobalt-60?
5.27 years
Answer:
| Type | Decay Mode | Half-Life |
|---|---|---|
| Co-60 | β decay, γ decay | 5.27 years |
| Tc-99m | γ decay | 8.01 hours |
| I-131 | β decay | 8.02 days |
| Tl-201 | electron capture | 73 hours |
What is the biological half life of cobalt-60?
9.5f days
Co-60 has a biological half life of 9.5f days, and an effective half life of 9.5 days.
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.
What is the isotope symbol for cobalt-60?

How is cobalt 60?
Cobalt-60 is produced by neutron bombardment of stable cobalt in a nuclear reactor. Small nickel-plated slugs of the radioactive metal are loaded into a sealed alloy cylinder typically 10 × 450 mm and doubly encapsulated in a corrosion-resistant steel pencil.
How do you find the half-life of cobalt-60?
Explanation: The half life is the time taken for the mass of the substance to decrease by a half. In this case, the amount of substance remaining is 20% of the initial amount (0.1 g out of initial 0.5 g). So it would take 2.32 half lives to decay this much, which is 2.32 x 5.2 which is 12.064 years.
How many individual decay steps are in the decay chain of uranium 238?
