Why is iodine-131 harmful to our bodies?
Ingested Iodine-131 is dangerous because it primarily affects the thyroid gland that plays a fundamental role in childhood development. Radioactive iodine toxicity varies greatly with age, with toddlers, young children and adolescents being far more sensitive than adults.
Where is iodine-131 found?
Iodine-131 is found in the gaseous and liquid waste streams of nuclear power plants, but is not released to the environment during normal reactor operations.
What are the benefits of iodine-131?
Because of this, radioactive iodine (RAI, also called I-131) can be used to treat thyroid cancer. The RAI collects mainly in thyroid cells, where the radiation can destroy the thyroid gland and any other thyroid cells (including cancer cells) that take up iodine, with little effect on the rest of your body.
What is iodine therapy used for?
Radioactive iodine (RAI) is treatment for overactive thyroid (hyperthyroidism) and certain types of thyroid cancer. The term “radioactive” may sound frightening, but it is a safe, generally well-tolerated, and reliable treatment that targets thyroid cells so there is little exposure to the rest of your body’s cells.
Where is iodine-131 used in medicine?
I-131 is used in medicine to diagnose and treat cancers of the thyroid gland. Where does it come from? I-131 is produced commercially for medical and industrial uses through nuclear fission. It also is a byproduct of nuclear fission processes in nuclear reactors and weapons testing.
Can I touch things after radioactive iodine?
You should try to keep all family and friends during this period at least one meter (three feet) away and do not have direct physical contact, especially intimate contact, like kissing or hand holding where radioiodine could be passed onto others.
Who discovered iodine-131?
The use of iodine-131 (131I), discovered in 1938 by Glenn Seaborg and John Livingood at the University of California, Berkeley, has been the success story in nuclear medicine.
Who produces iodine-131?
The shipment makes MURR the only supplier of I-131 in the United States and the first U.S. supplier since the 1980s. According to the American Cancer Society, thyroid cancer is “the most rapidly increasing cancer in the U.S.,”1 with diagnoses tripling in the last three decades.
How is iodine-131 used for diagnosis?
I-131 is a radioactive iodine salt that alters the mechanism of iodine absorption in the thyroid gland. Its use is particularly useful in the destruction of cells in the thyroid gland that are overactive. It can also be used in diagnostic imaging techniques used for pheochromocytoma and neuroblastoma.
When was iodine-131 first used in medicine?
This year marks the 75th anniversary since Saul Hertz first administered radioiodine (I-130–I-131) to a patient on January 1st 1941 in the Massachusetts General Hospital as a treatment for hyperthyroidism.
Where is iodine-131 used?
How long does iodine-131 stay in the body?
Most of the radioiodine not collected by your thyroid gland will be eliminated during the first two days after your treatment. It leaves the body primarily through your urine, but very small amounts may leave in your saliva, sweat and during a bowel movement.
¿Qué es el yodo radioactivo?
Usa yodo radioactivo para reducir o matar las células de la tiroides. Se utiliza para el tratamiento de algunas enfermedades de la glándula tiroides. La glándula tiroides tiene forma de mariposa y está situada al frente de la parte baja del cuello. Esta produce hormonas que ayudan al cuerpo a regular el metabolismo.
¿Cuál es la fórmula molecular del yodo?
Químicamente, el yodo es el halógeno menos reactivo y electronegativo. Como con todos los otros halógenos (miembros del Grupo XVII en la tabla periódica), el yodo forma moléculas diatómicas y por ello forma el diyodo de fórmula molecular I2.
¿Cuál es el número atómico del yodo?
El yodo o iodo [1] es un elemento químico de número atómico 53 situado en el grupo de los halógenos (grupo 17) de la tabla periódica de los elementos. Su símbolo es I (del griego ιώδης , iodes , “violeta”).
