Description

Key Advantages
Ultra-High Density (8.28 g/cm3)
One of the densest scintillators available, providing exceptional stopping power for high-energy radiation (e.g., gamma rays, positron annihilation photons). This enables compact detector designs while ensuring efficient absorption of even the most penetrating radiation??critical for space-constrained applications like PET scanners.
Fast Decay Time (6/30 ns)
Features a dual decay component, with a dominant fast component (6 ns) that minimizes signal pile-up in high-count-rate environments. This speed is invaluable for PET imaging, where rapid signal processing reduces scan time, and for particle physics experiments tracking fast-moving particles.
High Sensitivity to High-Energy Photons
Optimized for detecting energetic radiation (MeV range), making it highly effective in PET scanners (detecting 511 keV gamma rays from positron annihilation) and high-energy physics detectors (e.g., colliders, synchrotron experiments).
Non-Hygroscopic
Completely resistant to moisture, eliminating the need for protective coatings or hermetic sealing. This simplifies device integration, reduces maintenance costs, and ensures stability in humid environments (e.g., clinical labs or industrial sensor arrays).
