Expert Solution

Answer : (d) Co -60

Explanation :

Co-60 is used as anti-cancerous among the given radioactive isotopes. It emits β− particles and energetic gamma rays, for which reason it is used in radiation therapy. Cobalt 60 (60Co) is often the ideal mode of radiation for treating laryngeal cancer. For primary treatment of laryngeal cancer, 60Co allows adequate dosing of the superficial tissues.

d) Co-60
