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
Mentions of radioiodine in health care contexts refer more often to iodine-131 than to other isotopes. Of the many isotopes of iodine, only two are typically used in a medical setting: iodine-123 and iodine-131. Since 131 I has both a beta and gamma decay mode, it can be used for radiotherapy or for imaging.
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.

For this reason, people at risk of exposure to environmental radioactive iodine (iodine-131) in fallout may be instructed to take non-radioactive potassium iodide tablets. The typical adult dose is one 130 mg tablet per 24 hours, supplying 100 mg (100,000 micrograms ) of ionic iodine (the typical daily dose of iodine for normal health is on the ...
A gaseous leak of a radioisotope of iodine, 131 I, was detected at a large medical radioisotope laboratory, Institut national des Radio-Eléments. Belgian authorities implemented restrictions on use of local farming produce within 5 km of the leak, when higher-than-expected levels of contamination was detected in local grass.
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.
