Instructions for safe use of radiation shielding glasses

In order to use the high-quality RD 30® or RD 50® radiation shielding glass e.g. in the X-ray range it is essential to observe the following instructions in order to prevent loss of quality and to ensure permanent and safe operation. You should therefore take these notes to your records.


Installation of radiation protection glasses

  • Sealants:
    Only use acid- and alkali-free sealants for installation. Sealing agents containing acetic acid or ammonia, for example, are unsuitable.
  • Labels:
    Stickers or labels may cause staining on the glass surface due to the reaction of the adhesive with the radiation shielding glass.
  • Protective tape:
    Any protective films or plastic tape on RD 50® should only be removed after the glass has been installed. Do not use sharp-edged objects to remove the film.
  • Application environment:
    Radiation shielding glass may only be used indoors. The glasses are not suitable for outdoor use.
  • Installation regulations:
    For installation the on-site requirements according to DIN 6812 (Radiation protection regulations for the erection of X-ray systems) are imperative to be taken into account.
  • Radiation protection overlap:
    Ensure that sufficient radiation protection overlapping is ensured when installed.


Cleaning and maintenance instructions


  • Avoidance of scratches:
    Due to the high lead oxide content the surfaces of RD 30® or RD 50® can scratch more easily than normal glass. Also the materials react more sensitive to contact with acids and alkalis than normal glass. Therefore, only water and mild detergents and soft cloths may be used for cleaning. After cleaning the glass must always be wiped dry. Since RD 30® has a lower lead oxide content than RD 50® the surface of RD 30® is less sensitive than the surface of RD 50®.
  • Humidity:
    Radiation shielding glasses must never be exposed to moisture. Temperature fluctuations in connection with humidity as well as air that contains acids must also be avoided at all costs.
  • Disinfection:
    The disinfection of RD 30® and RD 50® radiation shielding glass can be carried out with commercially available disinfectants. Disinfection by means of UV radiation is also possible.
