The specific embodiment

With reference to Fig. 1, the present invention relates to be used to store, transport or dispose the doubtful safety device 1 that comprises the object of dirty bomb.This device 1 comprises housing 2.In Fig. 1, this housing is shown is placed on the ground and stands on the leg 16.Housing 2 can open and close, makes object 11 can be placed in the chamber of device 1.As shown in Figure 2, housing 2 can be the spherical shell that has two hemispherical shells or case half 3,4.Housing 2 can be by being connected to each other half one 3,4 or disconnecting and opening or closed.Housing is designed to tolerate up at least 500 and restrains the explosive loading of TNT (trinitrotoluene) in housing 2 implodes.Should be appreciated that in most of practical applications, housing will be designed to tolerate the blast more than the powder charge of 500 gram TNT.In some cases, detonation chamber is designed to can tolerate nearly 1kg TNT or 10kgTNT or even bigger may be suitable.Housing 2 is designed to sandwich plate at least partly, the midfeather portion 7 that this sandwich plate has the inner wall part 5 that is formed from steel, the outside wall portions that also is formed from steel and made by lead.Midfeather portion 7 is clipped between inner wall part 5 and the outside wall portions.

If this device is used to transport and/or dispose the object such as doubtful dirty bomb, expect that then this device can prevent that radiation leakage from going out.The lead that is used for intermediate layer 7 is the material that is suitable for preventing that the housing of radiation by chamber from spilling.Reason is that lead is that density is about 11350 kilograms every cubic metre heavy material.This feasible lead is very suitable for the electromagnetic radiation and the particle radiation that stop radioactive substance to send.But lead is relative softer material, therefore is not suitable for use in the housing that is used for blasting within it.Because the mechanical property of steel, for example elasticity of steel and tensile strength are so steel is the material that is fit to this purpose more.Steel can not stop radiation effectively as lead, and if replace lead to stop radiation with steel, then the steel layer is thicker than the lead layer with identical capability of resistance to radiation.Because these reasons, the present inventor has been found that the device that is fit to doubtful dirty bomb should have the housing based on the leaded steel combination.But the inventor also has been found that simply and is not suitable for use in being expected at the chamber that wherein will blast by the plumbous outer steel sheel that covers.Reason is that the blast that occurs in the steel sheel may cause plumbous coating to break, and lead layer is very easy to damage.The inventor also has been found that the design that the steel sheel that uses plumbous internal layer simply neither be suitable, because be easy to cause the refined lead layer to damage from the fragment of housing implode.But, can resist the destructive power of the blast that takes place in the chamber of safety device 1 and can prevent radiation leakage effectively based on the housing of sandwich design with middle lead layer and inside and outside steel layer.

The thickness in intermediate layer can be 10-30mm for example.In many practical embodiments, the thickness of midfeather portion 7 can be 25mm-30mm.The thickness of inner wall part 5 can be 20-40mm.In a practical embodiment of the invention, the thickness of outside wall portions 6 or wall member 6 can be in the scope of 5mm-20mm.Can make the thickness of outside wall portions 6 littler than the thickness of inner wall part 5.

Housing 2 is spherical shell 2 preferably, can certainly use the housing of other shape, for example cylindrical or cube.The reason of preferred spherical shell is, sphere is considered to optimum aspect the ability of the blast in housing 2 tolerance housings.
