Abstract: A kickboard made of an elongate board having a top surface and a bottom surface, wherein the board has front, rear, and side edges that border the top and bottom surfaces. The bottom surface of the board is substantially convex in shape within the front and side edges. The board has a pair of elongate channels of defined depth formed in the bottom surface. The channels extend longitudinally from the rear edge toward the front edge and taper in depth near the front edge. The channels provide a variety of comfortable, ergonomically designed hand grip positions and also provide stability to the kickboard.

Abstract: A self-supporting radiation shield includes a radiation protective sheet; and a skeletal frame for supporting the radiation protective sheet, the skeletal frame including a lower frame member including a semi-elliptical tubular base member mounted on casters and three vertically oriented outer telescoping members extending upwardly therefrom, an upper frame member including a semi-elliptical tubular chest member and three vertically oriented inner telescoping members telescopically received within the outer telescoping members for vertical adjustment therewith, and two arm hooks extending forwardly in an upwardly inclined manner from the free ends of the tubular chest member to permit arms of the user to extend in front of the shield while protecting the front and side portions of the body of the user, and a locking assembly for releasably locking the inner telescoping members at a desired vertical position with respect to the outer telescoping members, the radiation protective sheet being connected to the up
