A radiation shield is adapted to be disposed transversely across a subject supported on the surface of a procedure table to protect medical professionals working in front of the radiation shield from radiation being applied to the subject behind the radiation shield. The radiation shield includes a movable barrier positional to extend transversely across a subject supported on the surface of a procedure table. The barrier has a generally vertically-oriented lower section; a generally forwardly sloping intermediate section; and a generally vertically-oriented upper section, forwardly offset from the plane of the lower section. A side section extends outwardly and rearwardly from one side of the lower, intermediate, and upper sections of the barrier. There is a recess in the lower edge of the lower section for accommodating a portion of the body of the subject on the surface of the procedure table, with portions of the lower section on each side of the recess projecting downwardly below the surface of the procedure table. A plurality of flexible radiopaque flaps depending from the perimeter of the recess block radiation from penetrating the gap between the subject and the perimeter of the recess.
