Description
SrI2(Eu) Scintillation Crystal is an inorganic scintillation crystal. It delivers high light yield and good energy resolution. With no background radiation, it suits element isotope discrimination, medical imaging, and safety inspection. The material is strontium iodide.
SrI2(Eu) Scintillation Crystal specifications
Cylindrical, ~25 mm diameter by ~50 mm high. Density: 4.6 g/cm³. Decay time: ~1100 ns. Peak emission: 435 nm. Energy resolution: <3.0% (Cs-137). Light output: ~300% of NaI(Tl) for γ-rays. Non-proportionality: ~2% (60-1274 keV). Encapsulation: sealed. 300% light output triples the photoelectron statistics. 435 nm emission suits standard PMTs and SiPMs. Sealed encapsulation protects the hygroscopic crystal.
SrI2(Eu) Scintillation Crystal background advantage
No intrinsic background means cleaner spectra at low count rates. Weak sources stand out. Isotope lines separate more cleanly. False alarms drop in screening portals. Medical imaging benefits from the high light output.
Typical applications
Element isotope discrimination. Medical imaging. Safety inspection areas. Border monitoring uses high-resolution scintillators. Handheld identifiers gain accuracy with better resolution. Fixed monitors benefit from the stable response. For a fast alternative, see our LaBr3 Scintillator Detector.
