1. What is the difference between RD 50® and RD 30®?®?
RD 50® and RD 30® have been given their product names based on their respective density of min. 5.05 g/cm³ or min. 3.13 g/cm³ and differ with regard to their applications, especially with regard to the protective effect, which is significantly higher with RD 50®.
2. How is this protective effect measured?
The protective effect is usually specified for the use of lead as a shielding material. For other materials such as glass, the protective effect is indicated as the lead equivalent, i.e. to which lead thickness the shielding effect of the material is equivalent.
3. Which lead equivalents correspond to RD 50® and RD 30®?
RD 50® offers lead equivalent values of 1.4 mm to 6.3 mm, depending on tube voltage and glass thickness. RD 30® offers a minimum lead equivalent of 0.5 mm Pb in 6 mm glass thickness.
4. Do RD 50® and RD 30® meet the necessary standards for your areas of application?
RD 50® meets the requirements of DIN EN 61331-2 and IEC 61331-2 for radiation protection in medical X-ray diagnostics. RD 30® is used for medical electrical devices built according to DIN EN 60601-2-45.
5. How is radiation protection achieved for e.g. BGW > 6.1 mm Pb?
By Laminating two pieces of RD 50® glass together. The BGW adds up accordingly.
1. How are RD 50® / RD 30® installed properly?
In any case, it must be ensured that the radiation protection on the wall side and the radiation shielding glass overlap to ensure full surface, continuous protection against radiation. Spaces without radiation protection may not be i.e. no radiation protection material may be used "butt to butt". An overlap of the radiation protection materials must always be present.
2. How can a higher stability be achieved for movable elements (sliding door/wall)?
With laminated glass made of RD 50® with float glass on one or both sides (also tempered safety glass) to achieve a higher stability and/or surface protection of RD 50®.
3. Can RD 50® / RD 30® be processed into insulating glass?
Yes. It is only ever necessary to ensure that the radiation shielding glass is inserted on the room side. RD Glass must not be exposed to weather and environmental influences. We provide appropriate supplier addresses (specialists) for complete radiation protection systems such as doors, windows, pulpits, rooms.
4. Can scratches on RD 50® be subsequently polished?
Each individual case needs to be reviewed, it depends primarily on the scratch depth.
5. Can RD 50® / RD 30® be cut to size later (e.g. on site)?
In principle yes. However with RD 50, care must be taken that the glass cutter is not ground too sharply and that only a little oil is used. The cut should always be made from the edge and should be broken as soon as possible. However, lead glasses should always be cut by an experienced glazier.
1. How can RD 50® / RD 30® be cleaned? What has to be considered?
Please only use water, mild detergents and a soft cloth for cleaning so that the glass surface is not attacked.
2. Are there any cleaning agents suitable for RD 50® / RD 30®; sealants; disinfectants?
Yes, we can provide product names and manufacturers on request.
3. Can RD 50® / RD 30® burn?
No RD 50® / RD 30® are not flammable. The softening temperature of RD 50® is about 603 °C and for RD 30® about 620°C.
4. How can RD 50® / RD 30® be disposed of?
According to federal, state or county regulations. Observe local regulations. The lead in the glass is chemically bound and cannot be leached out. Grinding and polishing residues are hazardous waste and must be disposed of in accordance with legal requirements.
