Cadmium Tungstate Scintillation Crystals

CWOSC041230

All support customized drawings.

Cadmium tungstate (CdWO₄) scintillation crystals are self-activated luminescent materials. Characterized by low afterglow, high X-ray absorption coecient, elevated density, strong radiation resistance, non-deliquescence, and excellent stability, they represent the material of choice for core components in large-scale security inspection systems.

The company maintains a complete crystal processing production line, enabling customized fabrication of one-dimensional and two-dimensional arrays with various dimensions, as well as specialized shaped products.
