SCHOTT RD 50®Outstanding protection against gamma and x-rays

At a glance

Ensuring safety together in difficult situations

SCHOTT Radiation Shielding Glass provides excellent protection against gamma and X-rays. When it comes to shielding harmful radiation, no compromises are possible. This is why more and more customers in the fields of medicine, science, and industry are relying on radiation shielding glass from SCHOTT. Security made in Germany.


Plan together with architects and find the ideal solutions

SCHOTT is the only company in Germany that manufactures radiation shielding glass, and processes it directly in an expert manner.

Thanks to its high density, RD 50® offers high X-ray absorption even with relatively thin glass, and meets the requirements of the German Institute for Standardization, European Standardization and the International Electrotechnical Commission.
Upon request, SCHOTT processes its Radiation Shielding Glasses into various versions.
RD 50® Raiation Shielding Glasses are used in many areas of medicine, science, and industry, in particular in X-ray rooms, operating rooms, radiation stations, dental practices, radiology practices, laboratories and in material testing – in “glove boxes”, for example.


SCHOTT RD 50® for PET applications

Due to its special composition, RD 50® is also ideal for use in PET applications, and offers an excellent protective effect. RD 50® can thus be used in combination with PET and CT.


Disinfection of radiation shielding glass
  • Only use water, a mild detergent and a soft cloth
  • RD 50® can be disinfected using commercially available disinfectants that SCHOTT has approved. Disinfection using ultraviolet irradiation is also possible.
  • Radiation shielding glass should never be exposed to moisture or temperature fluctuations in conjunction with moisture and acidic air.
  • Only use a sealant that is free of acids and alkaline substances (e. g. acetic acid, ammonia) during installation. Adhesive labels can cause discoloration if the adhesive reacts with the glass surface.
  • Do not remove the protective film from Radiation Shielding Glass RD 50® until immediately before installation. Do not use any sharp objects to remove it!


Window or door installation with Radiation Shielding Glass

Please follow the on-site requirements of DIN 6812 when installing RD 50®. Sufficient radiation protection overlap must definitely be ensured during installation.
Let’s use all of the possibilities of the material together

Bored holes and cut-outs in desired sizes,  bent or screen-printing applications and sanblasting - take advantage of the wide variety of processing possibilities.
