Ceramic Scintillator

A scintillator is a substance that absorbs rays, such as X rays and gamma rays, and makes; them visible to the human eye. Scintillators are used primarily in X-ray computer tomography (CT) and other medical equipment, analytical devices, gamma radiation in nondestructive inspection equipment and devices for detecting radiation leaks. At Proterial, we have developed high-density, highly functional ceramic scintillators.
We propose a method to use materials tailored to your company.
Features of Proterial's Ceramic Scintillator
- 1Supersensitivity/Low afterglow
- 2Hight uniform sensitivity The central part of the wafer and the edges offer a uniform sensitivity.
- 3Maximized X-ray absorption coefficient The X-ray absorption coefficient is large, which enables the miniaturization of the scintillator.
