Applicazioni

Cesium iodide is used as an input phosphor in x-ray image intensifier tube of fluoroscopy equipment. It is also used as an equipment for electromagnetic calorimetry in experimental particle physics. It is often employed as a beamsplitter in Fourier Transform Infrared (FT-IR) spectrometers. Cesium iodide is an inorganic scintillator which is mainly used in experimental nuclear physics, high energy physics, nuclear medicine, nuclear tomography, environmental studies and many other fields of use. It is utilized in calorimeters and detectors and also employed as a phosphor in fluoroscopy equipments.

Note

Hygroscopic. Store in a desiccator to avoid moisture. Incompatible with strong oxidizing agents, strong acids and bases.
