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 the X-rays.
 
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 application.
 
Health protection.
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.

Schock resistant?

RD30 can be thermally temperd and supplied as safety glass (ESG).

Insulated glass?

RD50/RD30 can be processed so that it can be used as insulated glass.

Laminated 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 lead equivalency.
  • 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
    • Non-flammable
