Radioactive isotopes can be used as tracers to investigate the function and structure of internal organs, such as the thyroid gland.
The thyroid gland, located in the neck, absorbs iodine from the blood to synthesize hormones. An overactive or underactive thyroid can lead to metabolic health issues.
Explain how a radioactive isotope of iodine, such as Iodine-123, with suitable properties may be used as a medical tracer to investigate thyroid function.
