What is the half-life of Cobalt-60?
Half-life of Co-60 = 5,27 year by beta- emission (0.315 MeV max.)
What is the equation for transmutation of cobalt?
Cobalt-60 decay to nickel-60:Co-60------------Ni-60 + 1 electron + 1 neutrino + gamma rays
How many neutrons does a cobalt-60 atom have?
Since cobalt has an atomic number of 27, any isotope of it contains 27 protons and 27 electrons per atom. The isotope with mass number 60 contains (60 - 27) or 33 neutrons per atom.
Is cobalt 60 natural?
no it not natural it sythentic
What is half-life of cobalt?
5.27 years.
What is the half -life of cobalt-60?
Cobalt-60 has an 1/2 life of 5.24 years
The half life of cobalt 60 is 5.3 yers after 10.6years how much of the original cobalt 60 remains?
One quarter-Apex
The half life of cobalt 60 is 5.3 years After years 14 of the original amount of cobalt 60 will remain?
10.6 years
What is the half-life of Cobalt-60?
Half-life of Co-60 = 5,27 year by beta- emission (0.315 MeV max.)
What percentage of the initial radioactivity of cobalt-60 would be left after being stored for 32 years?
The half life of Cobalt-60 is 5.27 years, so 32 years is almost exactly six half lives. (Which is probably why the question is put this way). Every half life the activity halves, so after six half lives it is reduced by a factor 26, which is 64. Therefore the activity after six half lives is 1/64 of the original level, or 1.56 percent.
If cobalt-60 emits a gamma ray what is the product?
Cobalt-60
What is the 0-60 time for a 2005 Cobalt SS?
6 seconds
What is the half value layer for cobalt-60?
I would not use Co-60 for shielding. Did you mean, "What is the half value layer for some shielding (XXXXXXXX) using Co-60 as a source of gamma ray energy?
The half-life of cobalt-60 is 5.3 years After years 1 4 of the original amount of cobalt-60 will remain?
After twice the half-life, 1/4 of the original amount remains. After 3 times the half-life, 1/8 of the original amount remains. Etc.
How is cobalt-60 made?
Cobalt-60, or Co-60 (and sometimes 60Co), is an unstable isotope of cobalt. It is radioactive. Co-60 is made by a process called activation. In activation, a cobalt (cobalt-59) shape (a "slug" or "pellet") is lowered into an operating nuclear reactor and exposed to the neutron flux. The cobalt-59 will absorb a neutron and become cobalt-60, and the sample (now called a source) is then withdrawn from the reactor and put into a heavily shielded casket for storage. Once our source is secured, it is assigned a special Nuclear Regulatory Commission tracking number. This source was licensed before it was made, and it will be continuously tracked throughout its long, long life. The source is used for any one of a number of things, and a link is provided to a question on that subject. The Co-60 has a half life of 5.27 years, and as it decays to nickel-60, or Ni-60 (60Ni), it goes through a three-step decay process and is dangerously radioactive throughout the time it decays. Remember that the 5.27 year half life means that half the sample has decayed in 5.27 years. There is still a lot around, and half of the remaining half decays in another 5.27 years - still leaving a lot remaining. Depending on the size of the originally activated sample, it can take a long time for the level of radioactivity to go down to anything near a "low" level. It can take hundreds or thousands of years for the sample to decay to the point where it can be removed from storage in a heavily shielded container.
How is cobalt 60 and cobalt 59 the same element but have different mass numbers?
Cobalt 60 has an extra neutron buit that does not affect chemical properties
What is the equation for transmutation of cobalt?
Cobalt-60 decay to nickel-60:Co-60------------Ni-60 + 1 electron + 1 neutrino + gamma rays
