Most asked questions about radiation shield glass
Optimal radiation protection.
If X-rays penetrate the human tissue, there is risk of damage to
the tissue and organs.
RD50 and RD30 provide optimal protection, as it contains a high percentage of lead oxide, which absorbs
In RD50 the number "50" refers to a minimum density of 5.05g/cm3.
In RD30 the number "30" refers to a minimum density of 3.13g/cm3.
The selection of which glass is appropriate is determined by the lead equilvalent requierd for the particular
Radiation shielding glasses RD50 and RD30 provide the best protection for:
- Technicians monitoring the x-ray process in medicine and industry
- Technicians at mammography work stations (i.e. cancer therapy)
- Technicans in research and development (i.e. "glove-box")
The selection of RD50 or RD30 is depending on the allowable dose of radiation for the particular application.
Minimal glass thickness?
RD50 provides high radiation absorption with a minimal glass thickness.
RD30 can be thermally temperd and supplied as safety glass (ESG).
RD50/RD30 can be processed so that it can be used as insulated glass.
RD50/RD30 can be laminated.
Glass versus synthetic (acrylic) material
- X-ray protection glass RD50/RD30 is much thinner and lighter than acrylic materials with a comparable
- Thickness and wight comparison for a lead equivalent of 2.2mm Pb:
- RD50 thickness: 7.0-8.5mm / 0.28-0.33 in 43kg/qm/8.8lbs./ft2
- Acrylic thickness: 44.0-48.0mm/1.73-1.90 in 74kg/qm/15.1lbs./ft2
- RD50 and RD30 are always edge processed; acrylic is not.
- RD50 and RD30 are anti- static;therefore, they do not stain as easily
- RD30 can be thermally temperd
- Insulated glass can be processed
- Laminated glass can be processed
- Synthetic material absorbs moisture
- RD50 and RD30 are:
- More resistant to disinfectants
- More scratch resistant
