Abstract

Lanthanum Halides can be used as replacement for present glass scintillators sensitive used to detect gamma radiation such and Sodium Iodide (NaI). The family of Lanthanum Halides have about twice the density of present glass scintillators. This creates several advantages. Using a Lanthanum Halide as the scintillator means that either (1) the sensing element can be smaller for the same count rate or (2) the count rate can be higher for the same sized crystal. Smaller sensing element inprove the resolution of the measurement. Higher count rates inmprove the statistics of the measurement. The use of a Lanthanum Halides will also allow the gamma detector to be more easily designed to optimize the combination of count rate versus resolution.
