What is Cesium iodide?
The Uses of Cesium iodide
Cesium iodide (CsI) is a kind of ionic compound that has been widely used as scintillators in many areas such as X-ray image intensifier tubes, photocathodes, and display devices.
Cesium iodide is used in scintillation counters(Geiger counters) to measure levels of external radiation. It is also useful as a "getter" to remove air molecules remaining in vacuum tubes.
Cesium Iodide is a material with high γ-ray stopping power due to its relative high density and atomic number. For scintillation counting, it is used either in its un-doped form or doped with sodium or thallium.
CsI is resistant to thermal and mechanical shock. The physical characteristics of CsI are independent of the activator used. Compared to NaI(Tl), it is relatively soft and plastic, and does not cleave. Because it has no cleavage plane, it is quite rugged-which makes it well-suited for well logging, space research or other applications where severe shock conditions are encountered.
