X-ray shielded windows are commonly used in control rooms and other rooms of X-ray laboratories as inspection windows. X-ray shielded windows are manufactured in customised dimensions and can be made in a separate window frame or as sidelights of X-ray shielding doors integrated with a door frame.
The frame of an X-ray shielded window is made from steel galvanised profiles and as a standard covered with laminate on its external side, filled in with a lead sheet layer of an appropriate thickness. The sheathing of a window frame can be powder varnished according to the RAL palette or made from stainless steel, thus ensuring not only proper radiation protection, but also high aesthetic and hygienic properties. The glazing of X-ray shielded windows is made with a special type of glass containing not less than 18% of lead oxide. Depending on the type of glass and manufacturer's technology, the content of lead oxide ranges between 18% and 65%, and lead minimum density within the range from 3.13 g/cm³ to 5.05 g/cm³. Lead glass used as glazing for X-ray shielding windows has a proper ratio of lead content; specified in millimetres as the equivalent of lead sheet. The Pb ratio of glass shall not be lower than the ratio of a lead layer filling the door frame. The PB ratio for the whole window structure is determined individually in the radiation protection design for each X-ray laboratory. Most commonly used types of X-ray shielding windows are windows with Pb ratios between 0.5 mm and 3.0 mm with the voltage range 60-150 kV, however, we also implement technological designs more demanding in terms of radiological protection thickness. Lead glass in X-ray shielding windows features a high light transmittance and they are easy to keep clean. Lead glass in windows - both as single glazing and a multiple glazed window adjusted to the thickness of the structure, is fixed with a glazing PVC batten in a colour similar to the window frame.
are fixed with Ø8 wedge anchors through anchors from galvanised steel sheet. The junction of the window frame with the masonry wall is filled in with a layer of lead sheet to ensure the continuity of radiological protection in a room.
