Description

PbWO4 | Scintillation Crystal is one of the densest oxide-based scintillators known for its short radiation length, small Molière radius, and strong radiation hardness.

Lead tungstate (PbWO4) is one of the densest oxide crystals; it is distinguished by its short radiation length, small Molière radius, and strong radiation hardness. Its scintillation light output peaks between 440–550 nm with a fast component decay time. After irradiation with gamm rays, the degradation in the optical transmittance is not large up to 106 rad. PbWO4 is also an excellent photoelectric crystal due to its good performance in optical properties and stable physical and chemical features.
