Question

Cobalt- $60$ is commonly used in radiation therapy because it emits
 A.Alpha rays
 B.Beta rays
 C.Gamma rays
 D.X-rays

Answer 1

Hint: We have to know that, the job of the cobalt unit has halfway been supplanted by the linear accelerator. Which, can create higher-energy radiation, and doesn't deliver the radioactive waste that radioisotopes do with their orderly removal issues.

Complete answer:
We have to know that, the cobalt- $60$ is utilized as a radiation source in numerous regular mechanical applications, for example, in evening out gadgets and thickness measures. It is likewise, utilized for radiation treatment in clinics. We need to know that inadvertent openings may happen as the aftereffect of misfortune or ill-advised removal of clinical and modern radiation sources.
We have to see that, the cobalt treatment is the clinical utilization of gamma beams from the radioisotope cobalt- $60$ to treat conditions like disease. Starting, cobalt- $60$ was generally utilized in outer shaft radiotherapy (teletherapy) machines, which delivered a light emission beams, which was guided into the patient's body to murder tumor tissue. Since these "cobalt machines" were costly and required expert help, they were regularly housed in cobalt units. We need to remember that the cobalt treatment was a progressive development in radiotherapy in the post-World War II period yet is presently being supplanted by different innovations like straight gas pedals.

Note:
We have to know that, cobalt treatment actually has a valuable task to carry out in specific applications is as yet in far reaching utilize around the world, since the hardware is moderately dependable and easy to keep up contrasted with the cutting edge straight gas pedal.
