scintillation efficiency

physics

Quick Summary

Scintillation efficiency refers to the fraction of energy deposited by ionizing radiation in a scintillator material that is converted into light. This light is then detected and measured.1

Key aspects of scintillation efficiency:
* Process: When charged particles interact with a scintillator, they create excited atomic or molecular states. These states decay by emitting photons (light).1
* Measurement: The amount of light generated is a small fraction of the deposited energy, typically ranging from 3 to 15 percent for common materials. This fraction is the scintillation efficiency.1
* Materials: Both inorganic (like sodium iodide) and organic scintillators are used, each with varying efficiencies, decay times, and optical properties suited for different applications.12
* Application: Scintillation counters use this light emission to detect radiation and measure its energy.3
