Using lead products to develop X ray lead shields for all types of applications is not new. The first x rays were discovered in 1895 by Wilhelm Conrad Roentgen, and the first use of lead for shielding materials was not until the 1920s.
The specific types of X ray lead shields and the requirements for use that is used today was developed after 1940. This is when the use of high energy medical imaging equipment created an increased risk of radiation for those working in areas where the equipment was in use.
Today, there are very specific requirements in building codes and design considerations when creating areas where radiation protection is a concern. This includes specific information on the type of X ray lead shields and product that can be used given the type and level of radiation in use.
Whether the discussion is with wearable types of radiation shields or materials used for shielding in walls, dividers, and even glass, it is essential that the design provides the required level of coverage over the entire surface area.
This is an essential consideration in designing rooms, as angles, corners and joint areas can be very problematic to ensure the desired level of lead is present. Specialized products such as gypsum and plywood that is lead-lined are often the best option for flat surfaces, including walls and ceilings. These types of materials have extended flanges on the side, allowing full lead backing to ensure joint areas have the same level of X ray shielding.
X ray glass and specialized types of window frames are likewise effective for full coverage. To address any small gap area, loose lead or lead shot can be dropped into the area. The loose nature of this material ensures it spreads out to fill all spaces, even those that may be difficult to see once the construction is complete.
