Abstract

The invention relates to a manually operated transport carriage for an ionizing electromagnetic radiation-emitting freight, comprising a frame (2) that has rollers (1) and at least one lateral wall (3). The lateral wall (3) is designed such that the lateral wall (3) reduces the dose rate generated by the radioactive decay of the freight to ≤ 1/5, when the freight has a dose rate of 100 μSv/h at a distance of one meter when the radiation is unhindered, on the lateral wall (3) face (5) that faces away from the freight. As a result, a transport carriage is produced with which radiation emanating from radiopharmaceutical freight in particular can be reduced so that operating personnel can stay in the immediate vicinity of the transport carriage without risk of injury to life or health due to the radiation.

Description

Hand-operated dolly

The invention relates to a hand-operated

Transport trolley for an ionizing electromagnetic radiation emitting cargo, with a roll

comprising the chassis and at least one side wall. The invention further relates to a

Transport trolley arrangement with the trolley and a cargo exported as a radiopharmaceutical.

Hand-operated dolly are from the state of the

Technics known and used to transport cargo and general cargo, such as parcels and letters, and are of

Logistics service providers, such as transport companies, in

Warehouses, railway stations or airports. For this purpose, the trolley, which are also referred to as a roll container, on the one hand manually by means of a drawbar or in the train network by means of appropriate

Clutches of a tractor movable.

As a cargo to be transported is basically any good in question, that of a first place to a second place, even on larger, partly world-spanning

Distances, can be transported. In particular, when it comes to transport the cargo from one country to another, especially in transport to other countries

Continents, the freight often in one

Warehouse, preferably at an airport,

stored intermediately and then sent periodically or after collection of a sufficient number of freight by means of a transport aircraft as so-called air freight. During interim storage, the cargo remains for simplicity in the loaded state on the trolley, which then in the warehouse is parked accessible to operating personnel. Not infrequently, the goods are stored on the trolley for a few hours or even days, so that the operating personnel are vulnerable to the dangers potentially posed by the cargo, in particular if the freight is dangerous goods, ie one of which Danger to the general public, the life and health of humans, animals and / or other things can emanate.

Based on this situation, it is the job of

Invention to provide a trolley for cargo of the operator against outgoing from the cargo

Dangers, especially against ionizing

electromagnetic radiation, protects.

The object is achieved according to the invention by the subject matters of the independent claims. advantageous

Embodiments of the invention are specified in the subclaims.

In this respect, one solution of the invention is a hand-operated dolly for an ionizing electromagnetic radiation emitting cargo, with a rolling

comprising the chassis and at least one side wall, wherein the side wall is designed such that the side wall by the radioactive decay of

Cargoes generated dose rate on the side facing away from the cargo side wall when the cargo generates a dose rate of 100 ySv / h at unhindered emission in a meter distance, to -S 1/5, preferably to -S 1/10 and most preferably on -S 1/20 reduced. It is therefore an essential point of the invention that the side wall is designed such that the of the

Freight outgoing radiation, in particular ionizing electromagnetic radiation is attenuated by the side wall so that an outside of the trolley located operator himself over a longer

Period can stay next to the dolly, without the operator is harmed to life and health. This means that "radioactive" cargo, such as radiopharmaceuticals, can be stored on the trolley without health-causing personnel in the vicinity of the trolley during storage due to the radiation emanating from the radiopharmaceuticals.

Such cargo is often in from the IAEA

(International Atomic Energy Agency) standardized "type A packaging" and has a radioactive activity of about 400-900 MBq, producing such radiopharmaceutical cargo in one meter, for example

Distance a dose rate in the amount of about 100 ySv / h with unhindered radiation, so without a side wall between the radiopharmaceuticals and the operator is provided, with a typical transport index of 10 per packaging unit of the radiopharmaceuticals.

In other words, this means that the trolley according to the invention for the transport and storage of

Cargo resulting from the radioactive decay of the

Cargoes emits radiation, advantageously reduces the radiation so that operators do not experience sustained damage to their health by staying, even for a long period of time, in the immediate vicinity of the trolley. Basically, the trolley can be designed in terms of its chassis as any known from the prior art trolley, such as wheels, preferably as steering and

Bockrollenpaare, for example, as a lockable

Steering roller pairs, are executed. It is also provided that the trolley is hand-operated, so on the one hand moved by an operator, so for example can be drawn, but also on the other by means of a

Tractor, such as an electric tractor between the loading, unloading and / or parking positions can be moved. Under ionizing electromagnetic radiation is in

Prior art preferably referred to electromagnetic radiation with a quantum energy of over 200 keV, thus thus for example so-called gamma and / or

X-rays. When gamma rays enter the human body, the radiation energy in

Ionisationsvorgängen effectively, which can lead to damage to the human organism. Such damage affects, for example, the genetic material that already at

relatively low radiation doses can be damaged.

Although radiopharmaceuticals as the presently preferred cargo are transported primarily in the aforementioned IAEA standardized type A packages, it can not be ruled out that in the transportation of radiopharmaceuticals, particularly in the intermediate storage between loading and unloading on a trolley in a warehouse, operators the one of the

Radiopharmaceuticals emitting radiation health damage as radiopharmaceuticals, depending on the nature of

Medication, not only beta emitters, but also

Gamma emitters that are more material-permeable to beta emitters and more harmful to the human organism.

The invention now goes a completely new way by the trolley is equipped with side walls, which reduces the radiation emitted by the cargo, so preferably by the radiopharmaceuticals, namely the dose rate, to a fraction, namely less than one-fifth, preferably less as one tenth and most preferably less to one twentieth of the value

reduce an operator at unhindered

Radiation, without the provision of such

Sidewall, would have learned.

Likewise, it is also possible to define the comparative value for the dose rate with unimpeded radiation not as 100 ySv / h but as 50, 75, 150 or 200 ySv / h, each at a distance of one meter. With the term

"Radiation" is present in the radiation of radioactive

Materials meant, preferably ionizing radiation and most preferably ionizing electromagnetic radiation or gamma radiation. Furthermore, it is preferred that the side wall is configured along its entire planar extent in order to achieve the reduction of the radiation according to the invention. The dose rate is the dose recorded per unit of time, ie radiation

understand.

Basically, the side wall to form the attenuation of the radiation according to the invention may be configured as desired, but according to a particular preferred embodiment of the invention is provided, that the side wall is made of a material having a nuclear load number> 78, preferably as a lead wall and very particularly preferably as a lead sheet of Pb-99, 98. This means that, as a shielding material, any material with an atomic number> 78, that is to say an atomic number> 78, can be provided in relation to the radiation emitted by the freight

For example, platinum, gold, tungsten or mercury, but preferably the side wall as a lead wall

is executed, most preferably carried out along its entire extent surface as a lead wall.

The atomic number, as well as the density of the material, has an influence on the damping, with materials of high atomic number, such as lead, and

High Density Materials Compared to Lower Atomic Density or Lower Density Materials, Improved Absorption or Reduction by

cause radioactive decay caused radiation. However, the use of lead is much cheaper than the other materials mentioned above

realize and offer, especially at the

Radiopharmaceuticals as cargo expected typical

Dose rates, adequate shielding against the radiation occurring to prevent damage to health and life of operators. The particularly preferred embodiment as lead sheet also offers the additional advantage that such a sheet is particularly inexpensive and easy to manufacture, as it were a low weight of the sheet and thus also of the trolley can be achieved. According to another preferred embodiment of

Invention is provided that the side wall along its extension has a wall thickness of> 15 mm, preferably ^ 20 mm and most preferably ^ 30 mm. The term "along its extension" is the same

be interpreted that the wall thickness at any point of the wall has at least the aforementioned strength, so at any point forms the shield according to the invention against radiation. In this context, it is further preferred that the wall thickness corresponds to the tenth value thickness, ie the radiation has subsided after passing through this thickness to one tenth of its original intensity. According to a further embodiment of the invention, it is preferred that two steel sheets are provided, wherein the steel sheets cover the surfaces of the side wall on both sides. In principle, it is also possible in this context to provide only a single steel sheet which covers only a single surface of the side wall, in any case the provision of steel sheets protecting the side wall from damage and deformations, for example during loading or unloading of the freight items, so that the life of the side wall, and thus of the trolley, can be extended by such an embodiment.

In this context, it is particularly preferred that between the side wall and the steel sheet, a non-conductive color is arranged, wherein particularly preferably the non-conductive color as non-conductive

powder coated color is executed. By a

Such an arrangement is achieved that the two-sided steel sheets, which serve as protective walls for the side wall are provided, do not act as a galvanic element in the penetration of moisture, and thus the

Longer life of the side wall or the trolley, which also leads to reduced operating costs.

In principle, the transport carriage can be configured with only a single side wall, it being also possible for two side walls to be provided, which are designed, for example, as a front and rear end wall. According to a particularly preferred embodiment of the invention, however, it is provided that the trolley has three side walls, wherein the side walls are each connected to the chassis and U-shaped together and the side walls and the chassis are configured to receive a Euro pallet as cargo.

Preferably, the side walls each extend without a gap from the chassis, for example, to a height of 1 m away from the chassis. In this case, the side walls can also be arranged detachably attachable to the chassis, with the embodiment for receiving a Euro pallet a particularly simple loading or unloading, for example with a forklift, from the open side can be accomplished.

In this context, it is further preferred that a fourth side wall is provided, wherein the fourth

Side wall detachably connected to the transport carriage is connected such that in a closed position, the side walls enclose the cargo circumferentially and in an open position access to the cargo from outside the

Trolley is possible. This can be done by the

Freight emitted radiation on all sides reduced by the inventive design of the side walls so that operators can be anywhere outside the trolley, without health hazards arising from the cargo

to suffer emitted radiation. On the other hand, can be pivoted by the provision of closing means, the fourth side wall in a particularly simple manner, for example, for opening and closing, to continue despite a peripheral shield to allow easy loading and unloading.

In addition to the configuration with a circumferential side wall is provided according to another embodiment of the invention that the chassis has a bottom wall and / or a top wall is provided, wherein the

Bottom wall or the top wall is connected to the side wall and the bottom wall or the top wall the same

Texture as the side wall has. Thus, a radiation is not only in the direction of

Reduce side walls, but also in the direction of the bottom or the lid, so for example by design of the trolley as cuboid closed cube. Here, "equal quality" means that the bottom wall or the top wall is designed such that the

Bottom wall or the top wall, the dose rate produced by the radioactive decay of the cargo on the side facing away from the cargo side of the bottom wall or the

Lid wall, if the cargo produces a dose rate of 100 ySv / h with unobstructed radiation at a distance of one meter, reduced to -S 1/5, preferably to -S 1/10 and most preferably to -S 1/20.

Finally, it is provided according to a preferred embodiment of the invention that the trolley a drawbar and / or a coupling for moving or coupling the Has trolley to another trolley. Also, a locking device may be provided which, if the rollers of the trolley are designed as castors, preferably acts on both castors of the trolley simultaneously, so that blocks both a wheel as well as a pivoting movement.

The invention further relates to a trolley arrangement, with the transport vehicle described above and a cargo exported as a radiopharmaceutical. That's it
