DESCRIPTION

With the application of nuclear safety inspection technology in anti-terrorism and the continuous development of nuclear medical imaging, the requirements for light output and energy resolution of scintillation crystals are continuously improved. Efficient radiation detectors must be able to distinguish between different radioactive sources and for gamma-ray detection, scintillator materials with high energy resolution, high light yield, and a short decay time are required. Compared to traditional scintillation crystal materials, Eu:SrI 2 crystal has a higher light yield and better energy resolution. In addition,

Eu:SrI 2 crystal has lower hygroscopicity and can be stored in an environment with low water content with stable characteristics indefinitely. The emission wavelength of Eu:SrI 2 crystal is between 400-500 nm, which matches well with the mainstream PMT spectral sensitive region that is beneficial for the detection of scintillation photons. At the same time,

Eu:SrI 2 crystal is not sensitive to changes in ambient temperature which will make its application scene more extensive, such as Gamma ray spectroscopy, elemental isotope screening and scintillation detectors for safety inspection equipment, in industrial and medical CT, ultra-high resolution X-ray imaging, etc.

FEATURES High light yield Good energy resolution Nonproportional thermal dependence Excellent light output proportionality High density Large effective atomic number

APPLICATIONS Gamma-ray spectroscopy Elemental isotope screening Medical and industrial applications Safety inspection equipment Ultra-high resolution X-ray imaging
