Solution
Medical uses of Radioactivity:
- Gamma radiations obtained from cobalt-60 are used to treat cancer by killing the cells in the malignant tumor of the patient.
- The salts of weak radioactive isotopes such as radio-sodium chloride, radio-iron, radio-iodine are used for diagnosis and are known as tracers. These tracers are used to detect the suspected brain tumors and blood clots before they become dangerous.
- γ-rays are used to sterilize bandages, dressings, syringes and other equipment to make them free of germs.
