X-ray Protection Glass
Protection from X-ray radiation
The clinic‘s own Pediatric Catheter Laboratory diagnoses and, depending upon the diagnosis, sometimes treats heart defects directly using a cardiac catheter. However, the use of X-rays for accurate diagnosis is a necessity, and it is precisely here where the radiation protection glass RD 50 made by SCHOTT Spezialglas AG, Standort Grünenplan finds its application. A spacious cabinet equipped with various technical instruments and devices allows the easy monitoring of the X-ray room thanks to the enormous 4 m wide and 85 cm high (roughly 13 ft. wide and 3 ft. high) window made of RD 50 glass. The window consists of two panes, placed next to each other at the edges, which were cut at a 45º angle. For stability reasons, the RD 50 glass was ‘sandwiched’ between two panes of float glass. This process allowed the Gustav Graaf Co. of Hamburg to successfully produce the world’s largest, continuous single RD 50 pane without any optical hindrance. The glass has a very high density owing to its high lead content at over 65 per cent. This allows the glass to have high absorption values in spite of its relatively small thickness, offering fully reliable protection from X-rays. The glass meets the IEC 61331-2 and DIN 6841 industrial standards.
