X-Ray glass is often known as “Radiation Shielding” glass, or “Lead Glass” as it contains lead to screen out X-Ray radiation used in CT scanning rooms and the like. The high barium and lead content make the glass very heavy and it is rated according to the lead equivalent required for protection. The glass has excellent light transmitting capabilities.
The minimum lead equivalent options are normally 1.1, 1.5, 1.8, 2, 2.2, 2.5 and 3mm and the glass ranges from 6mm to 12mm. The glass is limited in size and is very heavy due to the lead.
