Used as a scintillation material in radiation detectors, particularly for gamma-ray spectroscopy due to its high light output and good energy resolution. Often doped with cerium to enhance scintillation performance. Suitable for applications in nuclear safeguards, homeland security, and medical imaging because of its ability to detect and differentiate radioactive isotopes efficiently. Also investigated for use in neutron detection when enriched with specific isotopes. Its hygroscopic nature requires encapsulation, but it offers advantages over traditional scintillators like sodium iodide in terms of density and stopping power for high-energy radiation.
