GR Premium
GR Premium is a multilayered gamma-ray shielding glass manufactured by laminating a Pro-GR with special cover glass panels. It is designed for PET-based diagnosis that uses gamma rays with higher energy to penetrate than X-rays for general diagnoses. GR Premium has excellent impact safety, and the surface of it will not stain or discolor when lead substances react to moisture or lipids, which helps to reduce the need for maintenance.
