Abstract
The present invention provides a method and construction for shielding a source of radiation. The method includes the step of surrounding the source of radiation with a granite wall. The wall provides a interlocking block construction which prevent the blocks from separating. The wall further includes foundation blocks positioned below a ground surface to stabilize the wall. Additionally, the wall includes cap blocks which have sloped top surfaces to deflect rain water.
Claims10
A method of attenuating nuclear energy emitted from spent nuclear fuel, including the steps of:
- providing a source of radiation;
- providing a plurality of granite block sections;
- forming a wall from the granite block sections which obstructs the source of radiation.
A secondary radiation attenuation shield for protecting a source of radiation, the source of radiation being positioned on a ground level the secondary attenuation shield comprising:
- a plurality of granite foundation blocks, the granite foundation blocks having a top surface, the top surface having a first mating portion, the foundation blocks being positioned partially below the ground level, the foundation blocks positioned to form a wall;
- a plurality of block sections having a top and bottom surface, the bottom surface including a second mating portion cooperative in interfacing with the first mating portion of the foundation blocks so that the foundation blocks and the block sections obstruct the source of radiation.
