Disinfection of radiation shielding glass

  • only use water, a mild detergent and a soft cloth.
  • RD 30® 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.
