Abstract
A collaborative study of relative hygroscopicity of
anhydrous halide scintillators grown at various laboratories is
presented. We have developed a technique to evaluate moisture
sensitivity of both raw materials and grown crystals, in which the
moisture absorption rate is measured using a gravimetric
analysis. Degradation of the scintillation performance was
investigated by recording gamma-ray spectra and monitoring the
photopeak position, count rate and energy resolution. The
accompanying physical degradation of the samples exposed to
ambient atmosphere was photographically recorded as well. The
results were compared with ben
