CsI(Na) Scintillation Crystal

Sodium-doped Cesium Iodide (CsI:Na) ranks among the industry’s brightest scintillation materials, delivering an impressive light output at approximately 85% of NaI(Tl). With a broad emission peaking precisely at 420nm, it is perfectly optimized for maximum efficiency when coupled with standard bialkali photomultiplier tubes (PMTs).Engineered to survive the most extreme conditions, ATR Crystal specializes in fully encapsulated CsI(Na) scintillators and custom detectors. Our advanced high-temperature variants are specifically designed to withstand operating environments above 150℃. Combining exceptional gamma-ray stopping power with unparalleled mechanical and thermal shock resistance, these robust crystals guarantee an extended operational lifetime. They are the definitive choice for critical, harsh-environment applications including deep-well logging, aerospace research, and heavy industrial monitoring.
