Radiation Shielding Glass


X rays allowed that penetrate human tissue, risks damage to tissue and organs. RD 50® and RD 30, provides optimum protection, as they contain a high percentage of lead oxide, which absorbs the rays.

In RD 50®, the number "50" refers to a minimum density of 5.05 g/cm³.
In RD 30, the number "30" refers to a minimum density of 3.13 g/cm³.

The selection of which glass is appropriate is determined by the lead equivalent required for the particular application.

Radiation Shielding Glasses RD 50 and RD 30 provide the best protection for:
Technicians monitoring the x-ray process in medicine and industry
Technicians at mammography work stations (i.e. cancer therapy)
Technicians in research and development (i.e. "glove-box")


The selection of RD 50® or RD 30 is dependant on the allowable dose of radiation for the particular application.

Benefits of RD glass:
RD 50 provides high radiation absorption with a minimal glass thickness
RD 30 can be thermally tempered and supplied as safety glass (ESG)
RD 50 / RD 30 can be processed so that it can be used as insulated glass
RD 50 / RD 30 can be laminated
RD 50 /30 can be shipped within 3-4 weeks after order receipt
Glass versus synthetic (acrylic) material
X-ray protection glass RD 50 / RD 30 is much thinner and lighter than acrylic materials with a comparable lead equivalency.

Thickness and weight comparison for a lead equivalent of 2.2 mm Pb:
RD 50      thickness:     7.0-8.5 mm - 43 kg/qm
Acrylic     thickness:  44.0-48.0 mm - 74 kg/qm
RD 50 and RD 30 are always edge processed; acrylic is not
RD 50 and RD 30 are anti-static; therefore, they do not stain as easily
RD 50 and RD 30 can be disinfected with UV-C
RD 30 can be thermally tempered
Insulated glass can be processed
Laminated glass can be processed
Synthetic material absorbs moisture whereas RD 50 and RD 30 are more: resistant to disinfectants / scratch resistant and less flammable.
