Cesium Iodide

Cesium iodide, CAS number 7789-17-5, is an inorganic compound with exceptional optical properties, making it ideal for radiation detection and imaging applications. You can get high-purity cesium iodide from Iofina, a global leader in iodine derivatives.

This compound serves several industries that widely use it in advanced technologies. However, it requires careful handling due to its moisture sensitivity and potential health hazards if ingested or inhaled. 

What Is Cesium Iodide?

Cesium iodide is composed of cesium and iodine. It appears as a colorless or white crystalline solid that is highly soluble in water and has a high refractive index, making it useful in optical applications. Unlike many other salts, it has low hygroscopicity and absorbs less moisture from the air, enhancing its stability. It also has excellent scintillation properties, emitting light when exposed to ionizing radiation — this makes it useful in medical imaging, nuclear detection and astrophysics. Cesium iodide is a critical material for specialized optics due to its wide transmission range from ultraviolet to infrared. 

Cesium Iodide Applications

Cesium iodide has a wide range of applications, primarily in high-tech and scientific fields. Its ability to efficiently detect X-rays and gamma rays makes it a preferred material in radiation detection. Here are key applications for this compound:

  • Scintillation detections: Engineers incorporate cesium iodide into scintillators used in medical imaging, nuclear physics and security screening to detect high-energy radiation. 
  • Infrared optics: Manufacturers use cesium iodide to produce infrared-transmitting windows and lenses for thermal imaging devices and spectroscopy equipment.
  • X-ray phosphors: The exceptional light output of this compound makes it useful in X-ray intensifying screens, improving imaging quality in medical and industrial radiography.
  • High-energy physics: Researchers use cesium iodide in calorimeters to measure specific energy levels in high-energy physics experiments.
  • Space technology: Due to its low electron work function, cesium iodide is useful in photoelectron emission applications, such as in space-based particle detectors and ultraviolet imaging systems.
