What does 131 mean in iodine?

A radioactive isotope of iodine with an atomic mass of 131, a half life of eight days, and potential antineoplastic activity. Selectively accumulating in the thyroid gland, iodine I 131 emits beta and gamma particles, thereby killing thyroid cells and decreasing thyroid hormone production.

How do you write iodine 131?

Iodine 131 | I2 – PubChem.

Is iodine a 131 isotope?

Radioactive iodine (I-131), an isotope of iodine that emits radiation, is used for medical purposes. When a small dose of I-131 is swallowed, it is absorbed into the bloodstream in the gastrointestinal (GI) tract and concentrated from the blood by the thyroid gland, where it begins destroying the gland’s cells.

What is the difference between iodine and iodine 131?

Iodine, in the form of iodide, is made into two radioactive isotopes that are commonly used in patients with thyroid diseases: I-123 (harmless to thyroid cells) and I-131 (destroys thyroid cells. RAI is safe to use in individuals who have had allergic reactions to seafood or X-ray contrast agents.

What is the half life of iodine I 131?

Iodine I 131 is a radioactive isotope of iodine with an atomic mass of 131, a half life of eight days, and potential antineoplastic activity. Selectively accumulating in the thyroid gland, iodine I 131 emits beta and gamma particles, thereby killing thyroid cells and decreasing thyroid hormone production.

What can sodium iodide 131 be used for?

Therapeutic solutions of Sodium Iodide-131 are indicated for the treatment of hyperthyroidism and thyroid carcinomas that take up iodine. Palliative effects may be observed in patients with advanced thyroid malignancy if the metastatic lesions take up iodine.

What is the mechanism of action of iodide ion I-131?

The mechanism of action of iodide ion i-131 is as a Radiopharmaceutical Activity. Iodide I-131 (as Sodium iodide I-131) is a radioisotopic drug used for the treatment and palliation of thyroid malignancy. Iodine-131 is notable for causing mutation and death in cells that it penetrates, which is due to its mode of beta decay.

What kind of damage does iodine 131 cause?

Iodine-131 is notable for causing mutation and death in cells that it penetrates, which is due to its mode of beta decay. As a result of beta decay, approximately 10% of its energy and radiation dose is via gamma radiation, while the other 90% (beta radiation) causes tissue damage without contributing to any ability to see or image the isotope.
