Abstract

A radiation protection device is disclosed in the embodiment of the present invention. The radiation protection device is used for a system which is configured to perform safety inspection of a cargo or a vehicle by a ray. The radiation protection device comprising: at least one container, and a radiation protection part disposed within the container. The radiation protection material may comprise at least one of concrete, sandstone, and water, or the radiation protection part may comprise a steel-lead protection wall or a concrete protection wall. With the radiation protection device according to the embodiment of the present invention, after the container is transported to the site, it can be directly put in place to be capable of shielding rays without needing operation or with only simple operation. The amount of on-site work, construction time, and construction cost are low.

First claim

The invention claimed is:

1. A radiation protection device for a system which is configured to perform safety inspection of a cargo or a vehicle by a ray, the radiation protection device comprising:
a plurality of containers, and
a radiation protection part disposed within each of the container,
wherein:
the radiation protection part comprises a protection wall, and the protection wall has a protection wall body and a flange portion extending from at least a portion of an edge of the protection wall body, and
the plurality of containers comprises a first container and a second container adjacent to each other, and the flange portion of the radiation protection part within the first container is configured to be adjacent to a first wall of the first container, and the first wall abuts a second wall of the second container, so that the flange portion lies in the path of at least one ray which would otherwise pass obliquely through the abutting first wall of the first container and second wall of the second container.

2. The radiation protection device of claim 1 , wherein:
the flange portion forms a predetermined angle with the protection wall body.

3. The radiation protection device of claim 2 , wherein:
the predetermined angle ranges from about 45 degrees to about 90 degrees.

4. The radiation protection device of claim 2 , wherein:
the predetermined angle comprises about 90 degrees.

5. The radiation protection device of claim 4 , wherein:
the protection wall body has a substantially rectangular shape, and the flange portion protrudes towards at least one of opposite sides, in a direction perpendicular to the protection wall body, of the protection wall body from at least one of four side edges of the protection wall body.

6. The radiation protection device of claim 1 , wherein:
the flange portion protrudes towards a side, in a direction perpendicular to the protection wall body, of the protection wall body from at least one of an upper edge and a lower edge of the protection wall body.

7. The radiation protection device of claim 6 , wherein:
the flange portion further protrudes towards opposite sides, in the direction perpendicular to the protection wall body, of the protection wall body from at least one of a left edge and a right edge of the protection wall body.

8. The radiation protection device of claim 1 , wherein:
the flange portion protrudes towards opposite sides, in a direction perpendicular to the protection wall body, of the protection wall body from at least one of a left edge and a right edge of the protection wall body.

9. The radiation protection device of claim 1 , wherein:
the protection wall body has a substantially rectangular shape, and the flange portion protrudes towards at least one of opposite sides, in a direction perpendicular to the protection wall body, of the protection wall body from at least one of four side edges of the protection wall body.

10. The radiation protection device of claim 1 , wherein:
the flange portion has a substantially flat shape.

11. The radiation protection device of claim 1 , wherein:
the flange portion has a substantially plate shape.

12. The radiation protection device of claim 1 , wherein:
the protection wall body has a substantially flat shape.

13. The radiation protection device of claim 1 , wherein:
the protection wall body has a substantially plate shape.

14. The radiation protection device of claim 1 , wherein:
the protection wall is integral or a one-piece wall, or composed of a plurality of separate elements.
