Radiation Shielding Glass, High Lead Content, Excellent Visual Clarity

Radiation Shielding Glass, also known as X-ray glass or lead glass, is leaded glass that provides shielding protection by absorbing the energy of radiation. Its high lead and barium content, and wide thickness range, provide optimum shielding against radiation. The glass can be optically clear or have a slight yellow. Typically, the thicker the glass, the higher the level of radiation shielding. It is primarily used in the medical industry to provide protection against gamma rays and x-rays.

A variety of sizes and thickness are available

Technical Notes: Data provided by the Public Health England (PHE). Attenuation measured using the narrow beam method, in accordance with IEC 61331:2014. The lead equivalent in mm Pb, defines the protective effect of the glass compared to a lead wall. Example: A glass with 2.0 mm Pb offers the same protective effect as a 2 mm thick lead wall.

Application

Radiation shielding glass is commonly used to protect professionals and patients in a wide range of healthcare, dentistry, veterinary and industrial environments. Typically, it can be divided into three major categories as shown below:

Observation viewing windows for x-ray rooms, radiation therapy rooms, angiography rooms, CT scan rooms, etc.
Screens for medical diagnostics.
Protection windows or glove boxes in laboratories.

The angiography room is equipped with radiation shielding glass as the viewing window

Care & Cleaning

As high lead content glass is more susceptible to staining, the following precautions need to be taken care for installation and cleaning.

Do not stick anything on the surface of the radiation shielding glass during the installation. When masking tape is used in caulking, remove it immediately after caulking and wipe off any tape traces with alcohol.
Do not use a wet cloth or water to clean the glass and immediately wipe off water in case of the glass becomes wet.
When the glass becomes dirty or marked with fingerprints, polish the surface slightly hard with a dry, clean cloth like gauze with alcohol. Wipe the glass again afterwards with a new, dry and clean cloth to completely remove the alcohol remaining on the surface.
