Correct Answer: Cobalt
Solution : The correct answer is Cobalt .
Radiotherapy, a cancer treatment method, employs the radioactive isotope cobalt-60. This isotope is instrumental in arresting the development of cancer through a process known as radiotherapy. In this treatment, the highly energetic gamma radiation emitted by cobalt-60 is precisely directed towards cancerous cells. The purpose of this targeted radiation is to effectively "burn" the cancer cells, helping to eliminate or control their growth while minimising damage to surrounding healthy tissues.
