Lead Fluoride - PbF is a highly effective gamma-ray absorber as a result  of its high density

and high Z. It is also very fast with a very short Radiation Length and Moliere Radius.


PbF2 scintillator crystal strengths:



PbF2 scintillator crystals have the following issues which should be noted:



Lead Fluoride - PbF2 - scintillator crystals are useful in diverse applications such as:
