10 Questions
What is responsible for creating scintillation in the crystal?
The deposition of energy by a photon through the photoelectric effect
Which property of the crystal determines the useful energy range and resolution that can be detected?
Density
What type of crystals have provided the best sensitivity for isotopes with energy levels between 50 and 150 keV?
