• Just like we use Cobalt_(60) for food preservation similarly, we can use Iodine_(131) is used for treatment of hyperthyroidism.

• The radioactive iodine is mainly used for treatment of hyperthyroidism in toxic multinodular goitre.

• The radioactive iodine upon reaching the thyroid tissue releases $\beta$ particles and $\gamma$ rays. the beta particles after entering the tissue destroys the tissue. This results in increased fibrosis of the thyroid gland and permanent cure of hyperthyroidism.

• The use of radioactive iodine is very advantages because it can be done as an outpatient procedure and it does not require any surgery.
