Why Is Thallium Used In NaI Detector? The doping of the NaI crystal with thallium improves the scintillation efficiency by improving the light emission due to the improved recombination by light emission of electrons and holes at the dopant site. Why the NaI crystal is activated with thallium Tl when used as a scintillator? Sodium
What Tools Are Required To Detect Gamma Rays? The Geiger-Mueller (GM) detector is a common portable instrument choice for a general laboratory radioactive material survey. GM detectors are capable of detecting alpha, beta, and gamma radiation. How can we detect the presence of gamma rays? Gamma rays are detected by observing the effects they have
What Is The Basic Principle Of Scintillation Detectors? The basic principle is the same for every scintillation-type detector: when radiation strikes the scintillator it causes it to give off photons of visible light (that’s the scintillation part). What is a scintillation process? Scintillation is the process in which the energy from a certain radiation interacting
