Material Notes:
Cesium Iodide activated by thallium is a scintillation material with high absorption power and can be used as an efficient gamma ray absorber. CsI:Tl is soluble in water, but is not hygroscopic in laboratory conditions. It has high resistance to mechanical and thermal shocks. CsI:Tl can be easily fabricated into wide variety of shapes and geometries. It can be also fabricated into detection matrices.Data provided by the supplier, MarkeTech International.
