CAS 7789-17-5: Cesium iodide
Description:Cesium iodide (CsI) is an inorganic compound characterized by its formation from cesium and iodine. It appears as a white, crystalline solid that is highly soluble in water, making it useful in various applications, including as a scintillator in radiation detection and in medical imaging. CsI has a high melting point and exhibits a cubic crystal structure, which contributes to its stability. The compound is known for its hygroscopic nature, meaning it can absorb moisture from the air, which can affect its handling and storage. Cesium iodide is also notable for its ability to emit light when exposed to ionizing radiation, making it valuable in the field of nuclear medicine and radiation therapy. Additionally, it has applications in the production of cesium-based compounds and in the manufacture of certain types of optical devices. Safety precautions should be taken when handling CsI, as it can be harmful if ingested or inhaled, and appropriate measures should be implemented to mitigate exposure.
