Abstract
Abstract A flexible radiation shield apron is disclosed. A characterizing feature of the apron resides in the provision of an encasing fabric sleeve unconnected to the sheets providing radiation resistance, in the areas generally below the waist of the wearer whereby such portions of the apron readily bend with the movements of the wearer. Preferably the sheets providing radiation protection are separated at their peripheries by portions of the encasing fabric sleeve which intrudes between the perimeters of the sheets below the waist further to increase suppleness.
