X-RAY
It is a well-known fact that X-Rays, unless properly controlled and directed, are very harmful to the human body and have even been known to cause death. As a consequence, various materials are being utilizes for the insulating of the X-Ray tubes. There are two general methods of securing this protection. One is by the use of protective plasters, such as barium sulphate plaster, and the other is the use of sheet lead. In the use of plaster there are couple of disadvantages. But sheet lead has none of these disadvantages and is consequently considered the best possible protection. The Advisory Committee on X-Ray Protection of the International Congress of Radiology specifically warns against the use of protective plasters in installations of over 75 kV.The thickness of lead required varies with the power of the X-Ray apparatus.
The thickness recommended by the Second International Congress of Radiology are presented in the accompanying table:
Recommended Thickness of Lead Shielding for X-Ray Rooms

SOUND PROOFING
Soundproofing is becoming ever more important because of the noise polluting our environment. Sheet lead is one of the basic materials for acoustic control systems, lead is an extremely efficient barrier material by itself or fastened to studs as part of a wall. Arslan Metal’s lead sheet products are widely used in different applications for sound proofing.
