To anyone who may still recall the early days of diagnostic radiography and its therapeutic derivative, radiotherapy, the ability to monitor a patient whilst they are undergoing examination or treatment, with no more protection against harmful radiation than a thin sheet of glass, must seem little short of miraculous. In the past, thick concrete walls and lead shielding was the only form of protection for the operator and allowed little opportunity to observe the actual proceedings. In time, the inclusion of a high percentage of lead oxide in the manufacture of glass proved to be the solution and one since perfected in the SCHOTT product known as RD50.

Developing such a product requires creating the ideal balance between its ability to inhibit the passage of ionising radiation sufficiently and to transmit visible light. The German manufacturer has achieved this balance perfectly with a product that contains 65% lead oxide by weight and a luminance transmittance of 85%. In practice, a panel just 3,1 mm thick can provide the same level of protection as lead sheeting of one or two tenths of a millimetre less in thickness, depending upon the power of the radiation source.

RD50 may be used in a wide range of applications within the field of healthcare, including basic radiology, MRI scanning, and nuclear medicine. In these situations, it may be employed to glaze both doors and observation windows. When used with special mitre joints and laminated with float glass, the windows can be enlarged considerably to provide maximum observation. In addition, with the use of multiple glazing units, it can be shaped to merge with the existing structure or to provide a customised viewing solution.

Also suitable for use in a variety of industrial applications and in the laboratories where radionuclides are prepared, SCHOTT RD50 complies fully with the requirements of the German, European, and international bodies responsible for setting the performance standards for radiation-shielding glass.

If, for example, one is to ensure that the sick who may be in need of an X-ray, a CT scan, or a course of radiotherapy are closely observed and that the heath of those tasked with observing them will also be protected, there is room for comprise. It is fortunate then that SCHOTT is a company that is uncompromising in its pursuit of quality and reliability. That it has been successful in its quest is borne out by the exceptional performance of RD50.

Equally committed to maintaining the highest standards, LIT Africa is a proud supplier of this radiation shielding glass and other world-class SCHOTT products.
