Potassium iodide is a component in the electrolyte of dye sensitised solar cells (DSSC) along with iodine. Potassium iodide finds its most important applications in organic synthesis mainly in the preparation of aryl iodides in the Sandmeyer reaction, starting from aryl amines. Aryl iodides are in turn used to attach aryl groups to other ...
For instance, potassium iodide (KI), administered orally immediately after exposure, may be used to protect the thyroid from ingested radioactive iodine in the event of an accident or attack at a nuclear power plant, or the detonation of a nuclear explosive which would release radioactive iodine.
If a person consumes a dose of one of these chemical compounds, his or her thyroid may saturate with stable iodine, preventing accumulation of radioactive iodine found after a nuclear meltdown or explosion.
Potassium iodide (KI) tablets can reduce the risk of cancer in some situations due to slower uptake of ambient radioiodine. Although this does not protect any organ other than the thyroid gland, their effectiveness is still highly dependent on the time of ingestion, which would protect the gland for the duration of a twenty-four-hour period.
Below are a series of examples of internal exposure. The exposure caused by potassium-40 present within a normal person. The exposure to the ingestion of a soluble radioactive substance, such as 89 Sr in cows' milk. A person who is being treated for cancer by means of a radiopharmaceutical where a radioisotope is used as a drug (usually a ...
The iodide ion is selectively taken up by the thyroid gland. Both benign conditions like thyrotoxicosis and certain malignant conditions like papillary thyroid cancer can be treated with the radiation emitted by radioiodine. [6] Iodine-131 produces beta and gamma radiation. The beta radiation released damages both normal thyroid tissue and any ...
Potassium iodide in a dose for nuclear emergencies. Iodine absorbed by the body is almost completely stored in the thyroid gland and has a biological half-life of about 120 days. If the iodine is radioactive (131 I), it can irradiate and damage the thyroid gland in high doses during this time. Because the thyroid gland can only absorb a limited ...
Potassium iodine saturates the thyroid gland with safe iodine and protects it against radioactive iodine. Incidence of pediatric thyroid cancer rose 200-fold in Belarus by 1994 from 1985 because of the radiation release following the explosion and fire at the nuclear plant. In some parts of the country, the cancer rate rose 2,000-fold.
