What is Cobalt 60?
Cobalt 60 (Co 60) is known to be synthetic radioactive isotope of cobalt with a half-life of about a half decade. It sends out 315KeV electronic and two beams of gamma rays at higher speed through beta decay. It is created synthetically in nuclear reactors. Better industrial production banks on neutron activation of scads of samples of the monoisotopic and mononuclidic cobalt isotope Co 59. Fathomable quantities are also created as a by- product of typical nuclear power plant operation and may be found out externally when leaks takes place.
The Applications of Cobalt 60 Tungsten Radiation Shielding
Because of its high density and excellent soaking characteristics against radiation, tungsten alloy can be extensively utilized in cobalt 60 tungsten radiation shielding to avert the damage caused by Co 60 radiation. The chief application of cobalt 60 tungsten radiation shielding are: blood irradiation, food irradiation, industrial radiography, leveling tool, laboratory mutagenesis, medical radiotherapy, pest insect sterilization, sterilization of medical equipment, thickness gauges and a tracker for cobalt in chemical reaction.
Why Use Cobalt 60 Tungsten Radiation Shielding?
In comparision to conventional radiation shielding materials like boron carbide and lead, tungsten alloy radiation shielding ensures better density with small capability. At the same, the weight of high density alloy can ensure the similar energy absorption as lead does using 1/3 less material. When the weight is fixed, better density and the thickness would be more thin. Tungsten alloy material can be manufactured with thinner thickness but high radiation soaking capacity in high density. Which is why tungsten alloy material is befitting for radiation shielding. Cobalt 60 tungsten radiation shielding is far more useful than lead materials for it is non-toxic property. During the fabrication of shielding, tungsten alloy radiation shielding is measured as per the needs of shield to decrease the multiple shielding materials' thickness.
