Crystal-Grade Materials

Inorganic halides such as cesium iodide or lanthanum bromide are widely used to make crystal grade materials for scintillation detectors used in medical imaging and other applications. Scintillation detectors are also used for such applications as the detection of gamma rays. In these devices, gamma rays are absorbed by crystalline materials, which then give off light. The amount of emitted light is proportional to the amount of radiation striking the crystals. The crystals used in these devices must be of high-purity. For medical devices, crystals are often doped with thallium in order to improve their performance.
