Lead Glass
protects against X-rays and gamma rays in the medical and technical field. In research works it also provides necessary safety screening. DESAG RD 50â is an extra dense flint glass. Its protective effect is based on its high content of heavy metallic oxides of nearly 70 per cent by weight. The lead oxide content alone is more than 65 per cent by weight. Therefore, a density of above 5.05 g/cm3 is reached, so that relatively small thicknesses fulfil all legal safety regulations. Radiation shielding glass DESAG RD 50â meets the requirements of DIN 6841. The protective capacity of a radiation shielding glass for X-rays is indicated by the lead equivalent, either in relation of lead thickness to glass thickness in per cent or in mm Pb.
