Scintillators have become essential materials in modern society since they find applications in diverse fields such as security screening, resource exploration, and medical imaging. NaI is widely used as a host material for scintillators, but its strong hygroscopicity limits long-term use. In this study, we evaluated the scintillation properties of NaBr, which exhibits lower hygroscopicity than NaI. In scintillation spectra, NaBr transparent ceramics exhibit some emission peaks due to self-trapped excitons and some lattice defects. The light yield of NaBr transparent ceramics is estimated to be 1,000 photons/MeV.
