How does a scintillator work? Purpose of scintillator

A scintillator is a material used to detect and measure ionizing radiation such as alpha, beta, gamma, or X-rays. The purpose of a scintillator is to convert the energy of incident radiation into visible or ultraviolet light. This light can then be detected and measured by a photodetector. Scintillators are commonly used in a variety of fields, such as medical imaging (e.g., positron emission tomography or gamma cameras), radiation detection and monitoring, high-energy physics experiments, and nuclear power plants. They play a vital role in detecting and measuring radiation in scientific research, medical diagnostics and radiation safety.


Scintillators work by converting X-ray energy into visible light. The energy of the incoming X-ray is completely absorbed by the material, exciting a molecule of the detector material. When the molecule de-excites, it emits a pulse of light in the optical region of the electromagnetic spectrum.
