Radiation Shielding Glass

Product catalog summary

Overview: Radiation shielding glasses are essential for transparent protection against ionizing radiation. They are used in various settings such as X-ray rooms, operating theatres, radiation therapy rooms, dental clinics, laboratories, and material testing facilities. Applications include observation windows, intercommunication windows, door glazings, panoramic glazings, mobile protection walls, and protective panels for check-up systems.

Material Specifications: The glass is supplied as polished plates cut to customer requirements, with a maximum size of 2.80 x 1.40 m for 7.0-8.5 mm glass. Other glass types can be cut to sizes between 2.00 x 1.00 m and 2.44 x 1.22 m. The glasses are packed in wooden crates.

Technical Data:

Optical Properties: Refractive Index nD is 1.76, and transmission at 550nm through a 5mm path is ≥ 85.0%.
Chemical Properties: Contains 48% Lead (Pb) and 15% Barium (Ba).
Mechanical Properties: Density is 4.8 g/cm³, Knoop Hardness is 440 kg/mm², Young’s Modulus is 62.7 GPa, Poisson’s Ratio is 0.23, and the Coefficient of Thermal Expansion is 81.8 x10-7/°C.

Radiation Shielding Glass - Lead Glass: This glass provides X-ray protection and is used for large surface control windows and mobile protection walls. The minimum lead equivalence varies with thickness and X-ray tube voltage, with weights ranging from 26.4 kg/m² to 96.0 kg/m².

RD 30 Glass: Used against X-scattered rays at mammography workstations, RD 30 meets IEC 61331-2 and DIN 6841 standards. It can be thermally toughened and supplied as safety glass. Available sizes and lead equivalents are specified for various tube voltages.

Installation Guidelines: Remove the protection film before installation, avoid sharp objects, and adhere to construction regulations (e.g., DIN 6812 in Germany). Ensure sufficient overlapping of the radiation shielding during assembly.

Eye Protection: X-ray protective glasses are available in two protection levels: FG 50 (front=0.50/side=0.50 mm Pb) and FG 75 (front=0.75/side=0.50 mm Pb). The lens transmit rate is not less than 80%, and frames are available in red, blue, and green.
