Description

CsI(Tl) | Scintillation Crystal is one of the brightest scintillation crystals used for gamma ray detection.

CsI(Tl) | Scintillation Crystal is a scintillation material with excellent mechanical properties. It has a light yield four times higher than that of BGO and radiation length shorter than that of NaI(Tl). With a broad emission spectrum from 350 nm to 700 nm, CsI matches well with photodiodes and is suitable for detecting heavy charged particles under strong gamma-ray background.
