Material Notes:
Calcium fluoride activated by Europium is light scintillators are used for detection of charged particles and soft gamma ray up to several hundreds keV. CaF:Eu is typically used for detection of beta rays due to its relatively small back scattering. It is not suitable for detection of high-energy gamma ray because has a small photo fraction. It is non hygroscopic and is relatively chemically inert.Data provided by the supplier, MarkeTech International.
