Abstract

A radiation tunnel of an X-ray test device is shielded in by means of a radiation protection curtain in order that no impermissible radiation emerges. The radiation protection curtain is constructed from plates which are connected to one another in a manner of a downwardly suspended flat-top chain and are produced from a plastics composite that absorbs X-rays.

Claims (28)

1. A radiation protection curtain comprising a plurality of plates that are connectable to one another in a manner of a downwardly hanging flat-top chain and are made of an x-ray-absorbing plastic composite,

wherein each of the plurality of plates has a top edge, a bottom edge and two side edges, the top edge and the bottom edge of each of the plurality of plates provided with at least one loop-shaped hinge element,

wherein a bottom edge of a first plate is hingedly connected to a top edge of an adjacent second plate, such the second plate is positioned vertically below the first plate in the chain, and

wherein one of the two side edges of each of the plurality of plates has a protruding edge, which facilitates the arrangement of two plates next to one another so as to provide overlapping edges.

2. The radiation protection curtain according to claim 1 , wherein a width of a plate is 10 mm to 90 mm, 15 mm to 40 mm, or about 20 mm.

3. The radiation protection curtain according to claim 1 , wherein a height of a plate is between 20 mm and 60 mm, between 30 mm to 50 mm, or about 40 mm.

4. The radiation protection curtain according to claim 1 , wherein the plates have smooth outer surfaces.

5. The radiation protection curtain according to claim 1 ,

wherein the top edge of the second plate has two spaced apart loop-shaped hinge elements and the bottom edge of the first plate has a single, centrally located loop-shaped hinge element, such that when the first plate is hingedly connected to the second plate, the single, centrally located loop-shaped element of the first plate is positioned between and aligned with the two spaced apart loop-shaped hinge elements of the second plate, and

further comprising a pin that is slid through each of the aligned loop-shaped hinge elements to connect the loop-shaped hinge elements together.

6. The radiation protection curtain according to claim 1 , wherein the bottom edge of the first plate is hingedly connected directly to the top edge of the adjacent second plate.

7. An x-ray inspection device for the examination of objects, particularly items of luggage, the device comprising:

a radiation tunnel through which a conveying device for the objects is configured to run, the radiation tunnel having an entrance and an exit;

a radiation source arranged in the radiation tunnel; and

a radiation protection curtain arranged at the entrance and/or the exit of the radiation tunnel such that radiation in the radiation tunnel is shielded outwardly by the radiation protection curtain, the radiation protection curtain comprising a plurality of plates that are connectable to one another in a manner of a downwardly hanging flat-top chain and are made of an x-ray-absorbing plastic composite,

wherein each of the plurality of plates has a top edge, a bottom edge and two side edges, the top edge and the bottom edge of each of the plurality of plates provided with at least one loop-shaped hinge element,

wherein a bottom edge of a first plate is hingedly connected to a top edge of an adjacent second plate, such the second plate is positioned vertically below the first plate in the chain, and

wherein the top edge of the second plate has two spaced apart loop-shaped hinge elements and the bottom edge of the first plate has a single, centrally located loop-shaped hinge element, such that when the first plate is hingedly connected to the second plate, the single, centrally located loop-shaped element of the first plate is positioned between and aligned with the two spaced apart loop-shaped hinge elements of the second plate, and

further comprising a pin that is slid through each of the aligned loop-shaped hinge elements to connect the loop-shaped hinge elements together.

8. The x-ray inspection device according to claim 7 , wherein the bottom edge of the first plate is hingedly connected directly to the top edge of the adjacent second plate.

9. A radiation protection curtain comprising:

a plurality of vertically hanging chains, each chain comprised of a plurality of plates connected adjacent to one another in a vertical direction,

wherein each of the plurality of plates are made of an x-ray-absorbing plastic composite,

wherein each of the plurality of plates has a top edge, a bottom edge and two side edges, the top edge and the bottom edge of each of the plurality of plates provided with at least one loop-shaped hinge element,

wherein a bottom edge of a first plate is hingedly connected to a top edge of an adjacent second plate, such the second plate is positioned vertically below the first plate, and

wherein the top edge of the second plate has two spaced apart loop-shaped hinge elements and the bottom edge of the first plate has a single, centrally located loop-shaped hinge element, such that when the first plate is hingedly connected to the second plate, the single, centrally located loop-shaped element of the first plate is positioned between and aligned with the two spaced apart loop-shaped hinge elements of the second plate, and

further comprising a pin that is slid through each of the aligned lop hinge elements to connect the loop-shaped hinge elements together.

10. The radiation protection curtain according to claim 9 , wherein the bottom edge of the first plate is hingedly connected directly to the top edge of the adjacent second plate.
