Nettet3. sep. 2016 · Scintillators for PET photon detection can be rated on four of their characteristic properties: The stopping power is the inverse of the mean distance traveled by photons before they deposit energy in the crystal. This length depends on density and effective atomic number ( Z) of the material.
