Used as a scintillator material in radiation detection devices due to its high density and effective stopping power for gamma rays. Commonly found in medical imaging equipment, such as positron emission tomography (PET) scanners, and in high-energy physics experiments for detecting electromagnetic radiation. Its ability to operate at room temperature and provide fast, efficient light output makes it suitable for real-time monitoring in nuclear and security applications. Also employed in X-ray and gamma-ray detectors for industrial and environmental monitoring.
