RD 30® is a lead-containing flat glass product that protects against gamma and X-rays. Such radiation is used in medical technology for diagnostic purposes, in radiation therapy, or in industrial material testing equipment. Because these types of radiation have a high potential to damage health, accidental radiation exposure must be prevented at all costs. For this reason, transparent openings in medical devices or viewing ports in doors to radiation areas are protected by radiation shielding glasses.
RD 30® from SCHOTT is the only radiation shielding glass product manufactured in Germany. It is an ideal and proven, high-quality solution for many applications. RD 30® is a monolithic glass that contains lead oxide and provides a lead-equivalent of ≥ 0.5 mm Pb at 56 kV (see table). The Pb value is a measure of how protective a radiation shielding glass is. It is expressed in mm Pb, which is equivalent to the shielding capacity of pure lead.
SCHOTT developed RD 30® specifically for safety in medical areas with lower levels of X-ray radiation, such as mammography workstations. At tube voltages of up to 150 kV, RD 30® offers a lead-equivalent Pb of ≥ 0.5 mm. It is also often used in industrial test equipment and is an important safety element in various scientific nuclear applications.
If you are searching for a window with higher lead equivalents or for thicker radiation shielding materials, please refer to our RD 50® datasheet.
