Description

Key Advantages
High Light Yield (38,000 Photons/MeV)
Emits intense blue light (peak wavelength: 415 nm) with a high photon count proportional to incident radiation energy. This strong output ensures excellent signal-to-noise ratios, enabling precise energy quantification and high-resolution imaging.
Superior Energy Resolution
Combined with its high light output, NaI offers exceptional ability to distinguish between gamma ray energies??critical for identifying specific isotopes (e.g., technetium-99m in nuclear medicine) or analyzing mixed radiation fields.
Broad Sensitivity
Efficiently detects a wide range of radiation energies (from keV to MeV), making it versatile for diverse applications, including gamma cameras (SPECT), PET scanners, and general radiation monitoring.
Fast Decay Time (264 ns)
Enables efficient signal processing in moderate-count-rate scenarios, such as clinical imaging or laboratory-based radiation detection, balancing speed with sensitivity.
Technical Specifications
Parameter Value Unit
