Schott RS 253 Radiation Shielding Glass
Categories: Ceramic; Glass; Optical

Material Notes: SCHOTT offers a selection of specifically developed Radiation Shielding Glasses for applications in nuclear energy production and nuclear waste treatment. RS 253 is not doped with CeO2. The glasses are optimized in terms of high initial transmission, radiation, discharge resistance and different shielding behavior. Customized radiation shielding windows for all kinds of nuclear installations can be designed covering a wide range of requirements. SCHOTT employs the same production equipment and processes as used for the production of optical glasses assuring outstanding high quality standards.

Applications: Glass blocks and plates for radiation shielding windows to be used in:

  • Nuclear power plants
  • Reprocessing plants
  • Waste treatment facilities
  • Nuclear research institutes
  • Isotope production facilities
  • Glove boxes
Supply Forms: Radiation Shielding Glasses are supplied as finished blocks and plates (window faces visual grade polished, lateral faces ground) ready for installation into shielding window frames.Advantages:
  • Superior internal transmission
  • Outstanding internal quality (bubbles/inclusions/striae)
  • Different shielding behavior allows custom window design
  • Enabling designs with very long service lifetime without failure due to discoloration or electrostatic discharge
  • Improved neutron attenuation in case of shielding windows for concrete walls
