Specification Parameter

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. NaI crystals 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. Yunjia proudly offers high-quality NaI Crystal products, designed to meet the rigorous demands of modern radiation detection systems. Our NaI Crystal, a key type of scintillation crystal, delivers exceptional light output, rapid response, and superior sensitivity, making it ideal for applications in medical imaging, environmental monitoring, and nuclear physics research.

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.

Yunjia 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.
