Definition
Noun 1. A radioactive isotope of iodine: Iodine-131 is a heavy, unstable form of the element iodine that emits radiation as it decays. It has a half-life of 8 days, meaning half of its atoms decay in that time. 2. A medical diagnostic and therapeutic agent: It is used in a sodium salt form (sodium iodide) to diagnose and treat thyroid conditions, such as thyroid disease and goiter.
Usage Examples
- Noun:
- The doctor ordered a scan using iodine-131 to assess the patient's thyroid function.
- Treatment with iodine-131 is a common therapy for an overactive thyroid gland.
- The half-life of iodine-131 is relatively short, at eight days.
Advanced Usage
- "Administer iodine-131": To give the isotope as a medical treatment or diagnostic tracer.
- The endocrinologist will administer iodine-131 to ablate the remaining thyroid tissue.
- "Uptake of iodine-131": Refers to how much of the isotope is absorbed by the thyroid gland, which is measured in diagnostic tests.
- The test showed a high uptake of iodine-131, confirming the diagnosis.
