The absence or low presence of cobalt can cause anemia.Ĭobalamin proteins use the corrin ring to hold the cobalt unit. The Electronic configuration of Co: Ar 3d7 4s2. Cobalt is a transition metal and the atomic symbol of Cobalt is Co. It makes up cobalamin, also called vitamin B12. Electronic configuration: It is the arrangement of electrons in the increasing order of energy in the shells of an atom. Biological function of cobaltĬobalt is needed in all animals and in humans as well. In the absence of nuclear war, the risk arises from improper maintenance or handling of radiotherapy units. This is why certain nuclear weapons called dirty bombs are created.
The source used has a radius of 2 cm and produces the presence of penumbral parts that diffuse the radiation that surrounds its direction. it is therefore difficult to be able to encapsulate it to avoid radioactive contamination.Ĭobalt-60 generates two gamma rays that have energies of 1.33 MeV and 1.17 Mev. Isotopes lighter than the stable Co-59 are primarily decayed by electron capture creating iron isotopes, while those heavier than the stable isotope are decayed by beta emission giving rise to nickel isotopes.Ĭobalt-60 is used in radiotherapy instead of radium because of its economic price and also because radium decays into radon and it is a radioactive element in the form of a gas. The atomic mass of isotopes of this element is between 50 amu and 73 amu. Cobalt also has four meta-states, each of which has half-lives of less than 15 minutes. The other radioactive isotopes have half-lives of less than 18 hours and almost all of them less than one second. The most stable are Co-56, Co-57 and Co-60 whose half-lives are 70.86 days, 271.79 days and 5.2714 years respectively. The boiling point of this element is 2927.85 degrees Celsius or 3200 Kelvin and the melting point is 1495.85 degrees Celsius or 1768 Kelvin. This chemical element has a gray tint, is metallic and belongs to the group of transition metals, its atomic number is 27 and it is represented by the symbol Co.
