Title: Composite shielding means and mounting means for x-ray machines

Abstract: A shielding means for an x-ray machine comprised of a base plate which removably receives overlays masking out selective portions of the base plate to control the passage of the x-rays therethrough. The overlays are generally identical and provided with co-operating removable securing means to permit the same to be stacked one on the other to vary the thickness thereof. Removable mounting rails position and maintain the shielding means on the x-ray machine.
