Description

[Detailed explanation of the idea]

0001

[Industrial application field]

The present invention relates to a shield that can prevent radiation emission.

0002

Various structures have been developed to prevent radiation from being emitted to the surrounding area.

0003

[Problem that the invention attempts to solve]

The conventional radiation shielding structure described above has the following problems. <B> Conventional radiation shields are mainly composed of heavy, integrated structures. I want to. Therefore, once it is constructed, it is difficult to change its shape etc. Met. <B> It was also not easy to form it into a complicated shape. ＜C＞Furthermore, as in the case of extending a shield that has already been constructed, add a part of it. It was also difficult to bend or transform. <d> For example, if various devices and equipment are placed in the corners of a structure, the remaining space The shape of is becoming increasingly complex. If you try to construct a shield in such a location, it will be difficult to construct a shield in such a location. This is extremely uneconomical as it requires shielding a large space surrounding the vessel.

[Purpose of this invention]

This invention was made in order to improve the conventional problems as mentioned above. Provides a radiation shield that can easily be constructed with a shielding function The purpose is to Additionally, the present invention provides a radiation shield that is easy to dismantle, remove, and change its shape. With the goal. In addition, this invention allows even complex spaces to be entered and exited to be easily enclosed in a minimum amount of space. It is an object of the present invention to provide a radiation shielding body that can be constructed as a shielding body.

[0005]

[Means to solve the problem]

The present invention is a shielding body used for shielding a radiation generating device, and is a shielding body that is used in a divided space. and a sphere with a radiation shielding effect, and the sphere is placed inside the divided space. It is a radiation shielding body filled with. The present invention also provides a shielding body used for shielding a radiation generating device, which is divided into A material that has the effect of shielding space and the surface of the sphere, which has a radiation shielding effect, from neutrons. The above-mentioned coat is placed inside the partitioned space. This is a radiation shielding body filled with tinging spheres. The present invention also provides a shielding body used for shielding a radiation generating device, which is divided into The space and the surface of the sphere, which has the effect of shielding neutrons, are made of materials that have radiation shielding effects. Therefore, the coated sphere is formed inside the partitioned space. This is a radiation shield made up of filling spheres.

[0006]

[Configuration of the present invention]

The present invention will be described below with reference to the drawings. <A> Sphere A group of spheres having a shielding function is used as a radiation shielding member. The sphere 1 is made of a material having a shielding function against gamma rays, for example, at its center. For example, a center ball 11 made of iron, lead, etc. is used. Although it is possible to use the sphere 1 as it is, it is also possible to use the sphere 1 as it is, but further A coating 12 may also be applied. When coating 12, use a material that has a shielding function against neutron beams. A coating 12 of such material is formed using the following methods. Then, a sphere 1 having a shielding function against gamma rays and neutron rays is formed. be able to. This coating 12 film not only has a shielding effect but also allows the spheres 1 to flow together. It also has an effective effect on the eyes. The dimensions of the spheres 1 are such that the particle size is such that spheres 1 with smaller diameters are successively interposed between the spheres 1. Configure with distribution in mind. In the above embodiment of sphere 1, the outer surface of the metal center sphere has a shielding function against neutron beams. The case where a material having the following properties is used has been explained. However, the shielding machine against neutron beams The central sphere is made of a material that has the ability to A similar effect can be achieved by forming a film of covering material. <B> Storage space For example, a hollow container made of acrylic is used as a space for storing the sphere 1. instructor A group of many spheres is stored in a container to form a block, and many of these blocks are If they are lined up, they can form a wall. Therefore, if a group of spheres can be stored inside, it is not necessarily a hexahedral container. There is no need to be a wall, and it can be stored by using one side of the existing wall and surrounding it with formwork, etc. All you have to do is create a storage space.

[0007]

[Effect]

Fill the above-mentioned acrylic space with the coated spheres 1 and make a block. Configure locks. If this group of blocks is placed at a predetermined position, a radiation shield can be constructed. Can be done. Depending on the shape of this container or the placement of blocks, it can be It can also be created. Furthermore, instead of using a separate container, use a part of the wall to surround it with formwork. Then, a space for storing the sphere 1 can be formed. For example, if the wall surface of the existing structure 3 has a complicated shape as shown in Figure 2, the shielding effect can also be achieved. can be achieved. That is, in such a case, the formwork 2 is erected on the surface of the recessed part of the existing structure 3. stop Then, by injecting the above-mentioned group of spheres into the storage space inside the formwork 2, the inside will be completely filled. Can be filled. It can also be used when the device 4 is installed in a corner with complicated entrances and exits, as shown in Figure 3. Ru. If irregular triangular gaps 5 occur in many places around the device 4 like this In this case, one or more surfaces of the deformed portion are surrounded by a formwork 2, as shown in FIG. Then, a group of spheres is injected into the mold 2. Then, the complex-shaped device 4 will be surrounded by a group of spheres, A solid shielding wall is constructed between the radiation source p and the worker M to reduce the radiation exposure of the worker M. can do. If you want to dismantle, transform, extend, or add to the shield formed in this way, the space will be It is sufficient to dismantle a part of the container and the formwork 2 to discharge the sphere 1 inside. Alternatively, if you use suction power or liquid, you can remove the inside without dismantling the structure or formwork 2. It is also possible to fluidize and discharge a group of spheres.

[0008]

[Effect of the idea]

Since the present invention is as explained above, it can be used as a shield of any shape as a radiation shield. The body is easy to make, and it is also easy to dismantle, remove, and change the shape. Also, when various instruments and devices are installed, deformed spaces may remain. Even when shielding a space with such a complex shape, there is no need to shield an excessive amount of space. , easily adapts to complex spaces, shielding required with minimal volume shielding can form a body.
