DE102009021624A1 - Radiation protection wall for shielding of low-energetic radiation such as X-ray radiation, comprises transparent or opaque plates, which are melted from treated, cleaned and recycled glass granulate of cathode-ray tubes with high purity - Google Patents

Abstract

The radiation protection wall (1) comprises transparent or opaque plates (3), which are melted from treated, cleaned and recycled glass granulate of cathode-ray tubes with high purity, are joined to a wall assembly (2), are glued at the joints (4) or inserted or glued in a supporting frame and are smooth or profiled at the outer sides, which form the joints during connecting the plates, so that the profile of one plate positively fits in the profile of the surrounding plates present in the wall assembly. The glass granulate of the cathode-ray tubes contains metal oxide. The radiation protection wall (1) comprises transparent or opaque plates (3), which are melted from treated, cleaned and recycled glass granulate of cathode-ray tubes with high purity, are joined to a wall assembly (2), are glued at the joints (4) or inserted or glued in a supporting frame and are smooth or profiled at the outer sides, which form the joints during connecting the plates, so that the profile of one plate positively fits in the profile of the surrounding plates present in the wall assembly. The glass granulate of the cathode-ray tubes contains metal oxide, in which the atomic weight of the metal of the metal oxide is equal or larger than its ions. The supporting frame is framed in a horizontal and vertical manner, where a horizontal supporting frame or a vertical supporting frame is contained in the wall. The plates are produced as clear transparent plates from pure funnel glass of cathode-ray tubes, and are produced from screen glass of cathode-ray tubes.

Description

The invention relates to a radiation protection wall, preferably for shielding low-energy radiation such as X-radiation. But it is also suitable for use in the shielding of higher-energy radiation. By the invention, it should be possible to supply glass from cathode ray tubes, which are no longer in use and should be disposed of, an economical and environmentally friendly reuse.

Radiation protection walls are currently mostly made of stable, opaque wall assemblies of various materials - for example concrete mixed with heavy metal oxides. For example, in X-ray rooms of medical facilities, radiation protection walls are present between the room parts of the X-ray machine and the area of the operating staff in order to estimate this against X-rays. So that the operating personnel can observe the patients on the X-ray machine during the X-ray, the radiation protection wall usually contains radiation-proof small windows. For this exemplary application, the radiation protection wall according to the invention should separate the area for the X-ray machine and the area for the operating personnel in the entire extent of the space. As a result, on the one hand the patient has a higher sense of security, because he sees at all times visually full extent that he is supervised by the operating staff. At the same time, operators from the other side of the radiation barrier, with complete protection against harmful X-ray radiation, have an overview of the X-ray patients and the X-ray room including the equipment.

From the DE GM 299 15 669 "Element for shielding radioactive radiation sources" in particular claim 6 is known, this consists essentially of waste glass, which was at least partially obtained from picture tubes. It is preferably shredded broken glass or placed in granular glass elements, which are melted by a melting process. The resulting glass melt is then poured into a suitable mold.

In a further description of the invention, the DE OS 44 26 197 "Use of a protective device" according to particular claim 8, this consists essentially of shredded television picture tubes and / or computer monitors with or without aggregates, fillers and / or binders, in the form of molten or granulated glass together with iron ore-containing waste for the production of metal glass. According to the main claim this protective device consists of a plurality of polymer and spherical cells in the order of 0.5-3 mm.

The disadvantage of the "element for shielding radioactive radiation sources" according to the DE GM 299 15 669 is the use of Altglasmischungen in conjunction with partial proportions of recovered from picture tubes waste glass. So no transparent to opaque property can arise. A pure use of waste glass derived from picture tubes, which allows only transparent to opaque properties, does not contain this disclosure. Another disadvantage of this invention is that of these elements space-dividing stable large walls are not feasible.

In the in the DE OS 44 26 197 described "use of a protective device" is particularly disadvantageous that this can not be transparent to opaque due to their structure of spherical cells in any case. It is also not clear how room-dividing, stable large walls can be realized from these elements.

The object of the invention is to provide a radiation protection wall, which consists of processed Bildröhrenaltglas high purity. By simple means, a stable space-dividing large wall should be feasible, which at the same time has transparent to opaque properties.

According to the invention, the object of creating a radiation protection wall is achieved by the fact that it consists of a wall dressing joined transparent or opaque plates, melted from recycled picture tube glass granules of high purity. As a result, the transparent or opaque property of the plates and the whole radiation protection wall is possible.

The transparent or opaque panels are glued to the joints. But it is also possible to insert or gluing the transparent or opaque plates in a support frame or to achieve the connection of the plates with each other by appropriate positive execution of the plate edges.

In order to improve the opaque properties or the radiation protection effect of the radiation protection wall, it may be expedient to carry out admixtures of metal oxides in the transparent or opaque plates melted from recycled picture tube glass granules. In this case, preference is given to admixing those metal oxides in which the atomic weight of the metal of the metal oxide is equal to or greater than that of iron. This measure also increases the radiation protection effect.

The support frame of the radiation protection wall can be designed horizontally and vertically.

In a simplified version but also only eleven horizontal support frame or eleven vertical support frame is possible.

The invention will be explained below with reference to exemplary embodiments. The figures show:

1 : A radiation protection wall 1 as a wall association 2 in which the transparent or opaque plates 3 in the joints 4 are glued.

2 : A radiation protection wall 1 as a wall association 2 in which the transparent or opaque plates 3 in a supporting frame 5 are inserted.

3 : A radiation protection wall 1 as a wall association 2 in which the transparent or opaque plates 3 in a horizontal support frame 5.1 , are inserted.

4 : A radiation protection wall 1 as a wall association 2 in which the transparent or opaque plates 3 in a vertical support frame 5.2 , are inserted.

According to the 1 are at the radiation protection wall 1 , transparent or opaque plates melted from recycled picture glass granules 3 to a wall association 2 joined and at the joints 4 glued.

As an expedient embodiment of the radiation protection wall 1 show the 2 to improve the stability like the transparent or opaque plates 3 in a supporting frame 5 are inserted or glued.

Another expedient and simplified training of the radiation protection wall 1 is in the 3 and the 4 can be seen in which the transparent or opaque plates 3 only in a horizontal support frame 5.1 , or a vertical support frame 5.2 , are inserted or glued ..
