5. Using the LaBr3Ce scintillation detector for mobile gamma-spectrometry
University essay from Lunds universitet/SjukhusfysikerutbildningenAbstract : When doing mobile gamma-spectrometry the equipment has for severaldecades been limited to NaI(Tl) and Ge-based detectors. Recent developements has led to a possible replacement of NaI(Tl)-based systems in the form of a new scintillation material: LaBr3:Ce (cerium doped lanthanum bromide). READ MORE
