The other radioisotopes of iodine are never used in brachytherapy. The use of 131 I as a medical isotope has been blamed for a routine shipment of biosolids being rejected from crossing the Canada—U.S. border. [40] Such material can enter the sewers directly from the medical facilities, or by being excreted by patients after a treatment
The beta particles emitted by the radioisotope destroys the associated thyroid tissue with little damage to surrounding tissues (more than 2.0 mm from the tissues absorbing the iodine). Due to similar destruction, 131 I is the iodine radioisotope used in other water-soluble iodine-labeled radiopharmaceuticals (such as MIBG) used therapeutically ...
Iodine-131 (usually as iodide) is a component of nuclear fallout, and is particularly dangerous owing to the thyroid gland's propensity to concentrate ingested iodine and retain it for periods longer than this isotope's radiological half-life of eight days. For this reason, people at risk of exposure to environmental radioactive iodine (iodine ...
It is used for diagnoses involving a large range of body parts and diseases such as cancers and neurological problems. [1] Another well-known radioactive isotope used in medicine is Iodine-131, which is used as a radioactive label for some radiopharmaceutical therapies or the treatment of some types of thyroid cancer. [2]
Iodine-131 (131 I) is the most common RNT worldwide and uses the simple compound sodium iodide with a radioactive isotope of iodine. The patient (human or animal) may ingest an oral solid or liquid amount or receive an intravenous injection of a solution of the compound. The iodide ion is selectively taken up by the thyroid gland.
[1] [2] When the iodine atom is a radioactive isotope (iodine-125 or iodine-131), it is used as an adrenal cortex radiotracer in the diagnosis of patients suspected of having Cushing's syndrome, hyperaldosteronism, [3] pheochromocytoma, and adrenal remnants following total adrenalectomy. [1] [2]

Tositumomab is a murine monoclonal antibody which targets the CD20 antigen produced in mammalian cell. [1] It was combined with iodine-131 to produce a radiopharmaceutical for unsealed source radiotherapy, Iodine-131 Tositumomab (branded as Bexxar), for the treatment of non-Hodgkins lymphoma. [1]
