(a)

Interpretation Introduction

Interpretation:

The explanation for how the ingestion of the given radioisotope can lead to a reduction in the function of the thyroid gland has to be given.

Concept introduction:

Radioactive Iodine:

• The cells which can concentrate iodine is thyroid cells and ${\text{I}}^{\text{131}}$ is very effective.
• It is used to cure hyperthyroidism.
• Usually one dose of ${\text{I}}^{\text{131}}$ is used to treat hyperthyroidism and complete destruction of thyroid gland occurs by ${\text{I}}^{\text{131}}$.
• The inflammation of the salivary glands, changes in the taste and dry mouth can be considered as the side effects of using radioactive iodine.

(b)

Interpretation Introduction

Interpretation:

The two risks and the benefits for a patient by using I-131 has to be listed.

(c)

Interpretation Introduction

Interpretation:

The time taken for a patient treated with I-131 to completely go the radioactivity from their body has to be given.
