FAQ’s Radiation Shielding Glass

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.
