Description

Key Advantages
High Density (7.13 g/cm3)
Exceptional stopping power for gamma rays and energetic particles, maximizing absorption efficiency and minimizing radiation penetration. This makes BGO ideal for detecting high-energy radiation in compact devices.
Excellent Light Output (8500 Photons/MeV)
Emits blue light (peak wavelength: 480 nm) with high photon yield, ensuring strong signal-to-noise ratios for precise energy measurement. The light output is linearly proportional to incident radiation energy, enabling accurate quantification.
Non-Hygroscopic (No Moisture Sensitivity)
Unlike hygroscopic scintillators (e.g., NaI(Tl)), BGO is completely non-hygroscopic, eliminating the need for hermetic sealing. This simplifies device design, reduces maintenance costs, and ensures long-term stability in humid environments.
Superior Energy Resolution
Combined with its high light output and low background, BGO offers excellent energy discrimination??critical for distinguishing between multiple radiation sources in mixed fields (e.g., multi-isotope PET imaging).
Zero Background Radiation
Free of radioactive impurities, ensuring no spurious signals that could interfere with low-dose measurements. This is essential for sensitive applications like small animal PET and low-level radiation monitoring.
Mechanical & Thermal Stability
With a Mohs hardness of 5 and a melting point of 1323 K (1050??C), BGO maintains structural integrity in high-temperature environments and withstands handling during device assembly.
