thyroid gland
Iodine 131 has a half-life of 8.0197 days. Barium has no half-life. So no, Iodine-131 is not more stable than barium-137.
The atomic number is the same as the number of protons in the nucleus of the particle. Therefore, every atom, ion, and isotope of iodine has an atomic number of 53 (regardless of its mass number).
The atomic number of Iodine is 53, and so one atom of Iodine has 53 protons. In order for the charge to be balanced, each atom of Iodine must also have 53 electrons.
Potassium iodide crystals have many uses:supplement added to table salt to prevent goitertablets taken to protect the thyroid from iodine-131 radioactivity in falloutradiation detection crystal in some scintillation countersetc.
Iodine-131 is not natural, matter of fact it is a synthetically produced isotope (im doing this for my science assignment aswell)
The Thyroid gland
The thyroid gland is often imaged using a salt of iodine-131 as this gland has a high uptake of iodine.
Iodine-131
Iodine-131
Iodine-131 is a radioactive isotope of the element iodine.
When conducting a thyroid scan, the patient needs to be given a dose of radioactive iodine by either swallowing or intravenously. During the scan, a gamma scintillation camera takes pictures of the thyroid gland from 3 different angles. The camera detects gamma ray emissions from the decay of the radioactive iodine. Thus the technology of the camera and the computer that generates the image of the thyroid gland are technologies used in conjunction with I-131
No. However one of the fission products produced is Iodine-131 and it appears in the fallout. Iodine-131 is a dangerous beta and gamma emitter with a halflife of 8.05 days, it concentrates in the thyroid gland and can selectively kill it or cause cancers in it. Fortunately the halflife is only just over a week, because it then practically disappears in about 5 to 6 weeks. This allows Iodine-131 contaminated food and drink (e.g. fresh milk) to be stored and then safely used when the Iodine-131 has decayed. This also makes it possible to protect the thyroid gland by saturating it with ordinary Iodine (usually as potassium iodide pills) until the Iodine-131 has decayed.
The iodine-131 in the fallout poisons the thyroid gland.
Iodine-131 was discovered in 1938 by Glenn Seaborg and John Livingood through their research on neutron bombardment of natural iodine. They found that radioactive iodine was produced in the reaction, leading to the discovery of Iodine-131.

Iodine-131 decays through beta decay by emitting a beta particle and a gamma ray. This process transforms a neutron in the iodine-131 nucleus into a proton, resulting in the formation of xenon-131.
When iodine-131 is ingested, it gets absorbed in the body and concentrates in the thyroid gland, where it emits radiation. An overdose can lead to acute radiation sickness, damage to the thyroid gland, and an increased risk of developing thyroid cancer. Treatment may involve administering medications to block the uptake of radioactive iodine and monitoring thyroid function closely.
