Lead tungstate (PbWO4) is a scintillating crystal discovered in the 1990s. It is one of the densest oxide crystals, with a density of 8.3 g/cm3, and is distinguished by its short radiation length (0.9 cm), small Molière radius (2.19 cm), and strong irradiation hardness. Its scintillation light output peaks between 450–550 nm, with a fast-component decay time in the range of 2–20 ns. After irradiation with γ-rays, degradation in optical transmittance is not large up to 106 rad. PbWO4 is considered a promising scintillation material for electromagnetic spectrometers in high-energy and nuclear physics experiments, as well as nuclear medicine.
