ABSTRACT:
A portable and collapsible radiation shielding device is provided for the protection of personnel and equipment from ionizing radiation. The shield has a plurality of horizontally elongated slats of radiation shielding material, such as lead wool, hung from a plurality of horizontally spaced apart chains at spaced intervals along the length of the chains. The slats are connected to the chains near their top edges so that when they are in their raised state the slats are suspended from the chains and arranged in an overlapping manner, like shingles, and when collapsed arrange themselves neatly side by side in a stack. The device also has a container adapted to receive the shield in its collapsed state, and a hoist and mast for raising and lowering the shield into and out of the container. The container further has wheels for facilitating moving the device to the desired location, and an outrigger for providing stability to the shield when raised. The mast is dissassemblable so that it can be stored within the container along with the shield when not in use. The container may also have an opening at an end to facilitate removal of the radiation shield from the container when it is supported by means other than the mast.
