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.

Claims

1. Radiation shielding apparatus for use in conjunction with a pad on a table, said apparatus comprising a plurality of units, each unit comprising a pair of joined substantially flat orthogonal flaps, said flaps being formed of a radiation shielding material and adapted for removable placement under said pad, whereby one flap contacts said table and the other flap extends vertically from an edge thereof.

2. Apparatus as defined by claim 1 wherein each of said flaps comprises a sheet of high density shielding material affixed to a supportive sheet of rigid material.

3. Apparatus as defined by claim 1 wherein said plurality of units comprises five units proportioned to fit as a set around three sides of a rectangular table.

4. Apparatus as defined by claim 3 wherein two of said units are identical and each has an asymmetrical trapezoidal flap, and two others of said units are also identical but each of said two others has a trapezoidal flap which is of reversed orientation with respect to the trapezoidal flap of each of the first-mentioned two units.

5. Apparatus as defined by claim 4 wherein the last of said units is rectangularly shaped.

6. Apparatus as defined by claim 4 wherein each of said flaps comprises a sheet of high density shielding material affixed to a supportive sheet of rigid material.
