Radiation Shielding Glass
Can RD 50®/RD 30® be used to make insulating glass units?
Yes. However it needs to be considered that the radiation shielding glass is fitted on the internal side. It should not be subjected to any weathering or environmental influences.
Can RD 50©/RD 30® be thermally tempered?
RD 50 cannot be thermally tempered.
RD 30 can be thermally tempered. Also in monolithic safety glass quality with the appropriate stamp on request.
Can I cut RD 50®/RD 30® myself (e.g. at the installation site)?
In principle yes. With RD 50 you must be careful that the cutting wheel is not ground too sharply and only a small amount of cutting oil is used. The cut should always start at the edge, and the glass should be snapped off immediately if possible. Always ensure that the glass is placed on a suitable clean surface for cutting to avoid surface scratches.
Lead glass should always be cut by an experienced glazier.
What is the proper RD 50®/RD 30® installation method?
We can provide you with sketches showing 2 possible installation methods. One of these is installation in a normal window and the other is what is known as a speaker window.
However, care must be taken without fail to ensure that the radiation protection on the wall side and the radiation shielding glass overlap to ensure total and complete protection against radiation. There should be no gaps without radiation protection, i.e. radiation shielding materials should not be butted up to each other "edge to edge". The radiation shielding materials must always overlap.
How can RD 50®/RD 30® be disposed of?
There are two possible ways to dispose of RD 50/ RD 30:
a) Any scrap can be taken to at a normal household waste disposal site. This can be done as the lead is a chemical component of the glass and cannot be leached out.
b) The scrap can be collected and sold to a company that manufactures lead compounds. This possibility is only worth considering when the price of lead traded on the commodity markets is high.
Both variants only apply of course to glass offcuts. They do not apply to cutting and grinding residue (powder, slurry, etc.) or other waste.
Does RD 50®/RD 30® burn?
No. RD 50/RD 30 are not flammable. The softening point of RD 50 is about 603°C and of RD 30 about 620°C.
Acrylic on the other hand is flammable, so it will burn. The softening point of plastics is about 100°C to 300°C. If the flames go out, e.g. if they are extinguished or run out of air, poisonous decomposition products (e.g. toxic gases) continue to be released as a result of the effect of the heat.
What is the proper way to clean and look after RD 50®/RD 30®?
See our flyer "Installation, cleaning and maintanance of radiation shielding glass" which you can print out yourself. If you would like this please click here.
