Why Is Thallium Used In NaI Detector?

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 Is Detector Efficiency Dependent On?

What Is Detector Efficiency Dependent On? For a given detector, efficiency values depend on the type and energy of the incident radiation. … For incident charged particles such as alpha particles or beta particles, many detectors have a total efficiency that is close to 100 percent. Does the efficiency of a gamma detector increase or
