RD 50® is a clear transparent dense flint glass which is produced by SCHOTT in Germany. The modified lead-silicate glass is used for shielding X-rays and gamma radiation in medical and industrial applications as well as in research. It has a lead oxide content of > 65% by weight which results in a density of at least 5.05 g/cm2 and thus enables compliance with statutory safety regulations even at comparatively low glass thicknesses. RD 50® has an increased lead equivalent compared to RD 30® and therefore has a higher radiation shielding effect. The X-ray absorption of RD 50® can meet the requirements of the German Institute for Standardization (DIN Germany), European Standardization and the International Electrotechnical Commission. The special composition of RD 50® allows the radiation shielding glass to be used in positron emission tomography (PET) and computer tomography (CT) as well as its combination. The glass is available in a wide range of standard thicknesses. In many cases, it can be polished to custom thicknesses too.
