Most elements have different isotopes, with different numbers of neutrons. Once source to get more information about the cobalt isotopes is the Wikipedia article on Cobalt - look for the section on isotopes.

Is positively charge neutron?

No, a neutron does not have a positive nor a negative charge. Its in between, too many neutrons can cause radiation, like cobalt-60 the number at the end tells you how much neutrons are in the atom.

What compounds are in cobalt?

There are no compounds in Cobalt. It is completely impossible, because Cobalt is an element, and compounds are made up of elements. If this is what you meant to ask, then there a a lot of compounds with Cobalt in them. One example is Cobalt (III) Fluoride, chemical formula CoF3. Any compound with a "Co" (the "C" must be capitalized and the "o" must lowercase) in it contains Cobalt.


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.


What is neutron capture?

In short, neutron capture is a nuclear reaction wherein an atomic nucleus captures one (or perhaps more) neutrons. The nucleus is then one nucleon heavier (or perhaps more, if more neutrons are absorbed). The new nucleus may be subject to further transformations, depending on what was formed in the capture process. Many different atomic nuclei can capture a neutron under the right conditions. We often think of uranium or plutonium (nuclear fuels) as atoms that undergo neutron capture. It is, after all, neutron capture that destabilizes the nucleus and can cause nuclear fission. This is the process that we set up when we build a nuclear reactor or a nuclear weapon. We can expose any number of different materials to the neutron flux in operating nuclear reactor. Atoms in the material will undergo neutron capture, depending on the conditions in the ractor, and (primarily) what the material is. In the case of cobalt, we will lower a measured amount of the metal in a suitable form into the reactor via a port. After a desired amount of time, the slug of cobalt, which was cobalt-59, is withdrawn. We now have a slug that has a fair percentage of cobalt-60 in it, and cobalt-60 is radioactive. The isotope emits gamma rays, and the slug is put in a casket of shielding material and can be transported for industrial use. (It might be used to X-ray welds in piping at a remote location, or sterilize band aids or other medical items at the end of a manufacturing process.)

Where did the cobalt bomb originate?

The cobalt bomb is a modified hydrogen bomb containing a jacket of cobalt. Natural cobalt is isotopically pure stable cobalt-59 and when it captures a high energy fusion neutron it transmutes to the highly radioactive isotope cobalt-60. This dramatically increases the fallout produced. The cobalt bomb was proposed for use as an area denial weapon, as the cobalt-60 fallout contaminated area would be completely uninhabitable for roughly 25 years. But it never made it to development as an actual weapon by any country. You simply cannot control where the fallout will go or its distribution, making it as dangerous to the army using it as to the army it is used on.
