Abstract

Abstract Radiation shielding apparatus for use in conjunction with a pad on a table. The apparatus comprises a set of units, each unit comprising a pair of joined substantially flat orthogonal flaps. The flaps are formed of a radiation shielding material and are adapted for removable placement under the pad whereby one flap contacts the table and the other flap extends vertically from an edge thereof. In a preferred embodiment of the invention the set consists of five units that provide protection around three sides of a rectangular table. In this embodiment, two of the units are identical and have asymmetrical trapezoidal flaps, and two others of the units are also identical, but have trapezoidal flaps which are of reversed orientation with respect to the first-mentioned two units.
