NaI(Tl) (Sodium Iodide) crystals are known for their exceptionally high scintillation efficiency, making them one of the most commonly used materials for radiation detection. They generate some of the highest signal outputs in photomultiplier tubes (PMTs) based on the amount of radiation absorbed. The emission peak of NaI(Tl) closely aligns with the spectral response of PMTs that use bialkali photocathodes, allowing for highly efficient light detection.
These crystals are extensively applied in a wide range of radiation detection scenarios, including nuclear medicine, environmental monitoring, nuclear physics, aerial radiometric surveys, well logging, and more.
EBO provides custom fabrication of NaI(Tl) crystals in various sizes and geometries to suit specific application needs. However, since NaI(Tl) is hygroscopic—readily absorbing moisture from the air—it requires careful handling and appropriate storage conditions to prevent performance degradation and to ensure long-term reliability.
