A canister for transporting/storing radioactive materials, comprising two concentric shells between which is housed a radiological protection device forming a barrier against gamma radiation, comprising a first and a second metal radiological protection components superimposed along a radial direction of the canister, the first component being supported against the outer shell and the second component being supported against the inner shell. In addition, the components are in contact with each other along an interface taking, in section along any plane integrating the longitudinal axis, the form of a straight line segment inclined in relation to this axis.

1. Canister for transporting and/or storing radioactive materials, said canister comprising: a lateral body extending around a longitudinal axis of said canister, said lateral body forming a cavity for housing radioactive materials and comprising an inner metal shell and an outer metal shell, the two shells being concentric and forming jointly an annular space inside which is housed a radiological protection device forming a barrier against gamma radiation,wherein said radiological protection device comprises at least one first and one second metal radiological protection components superimposed along a radial direction of the canister, said first component being supported against the inner shell and said second component being supported against the outer shell,wherein said first and second components are in contact with each other along an interface taking, in section along any plane passing through said interface and integrating the longitudinal axis, the form of a straight line segment inclined in relation to this axis, and wherein the inclined straight line segment is inclined at a non-zero angle with respect to the longitudinal axis,wherein the first and second components are wedged between the inner metal shell and the outer metal shell, wherein the first component is in direct surface contact with an outer diameter of the inner metal shell and the second component at the interface, and wherein the second component is in direct surface contact with an inner diameter of the outer metal shell and the first component at the interface, andwherein the position of each of the first and second components between the inner metal shell and the outer metal shell is maintained only by the direct contacts between the inner metal shell, first component, second component and outer shell in the annular space. 2. Canister according to claim 1, wherein that said inclined straight line segment forms with said longitudinal axis an angle (A) between 1 and 10° . 3. Canister according to claim 1, wherein said interface between said first and second components is flat or truncated. 4. Canister according to claim 1, wherein interface is flat and takes, in any section along a plane orthogonal to the longitudinal axis, the form of a straight line segment orthogonal to a radial line passing through its center. 5. Canister according to claim 1, wherein said interface is truncated and coaxial with the inner and outer shells. 6. Canister according to claim 1, wherein the outer surface of the first component supported against the outer shell is of straight section or arc of circle shape of diameter identical to that of the inner surface of the outer shell against which it is supported, and in that the inner surface of the second component supported against the inner shell is of straight section or arc of circle shape of diameter identical to that of the outer surface of the inner shell against which it is supported. 7. Canister according to claim 1, wherein said first and second components have an identical or different circumferential span. 8. Canister according to claim 1, further comprising a plurality of first metal radiological protection components and a plurality of second metal radiological protection components, each first component being supported radially uniquely on one of said plurality of second components, and inversely. 9. Method for producing a canister according to claim 1, wherein firstly one of said first and second components is put in place in the annular space, then the other of said first and second components is inserted longitudinally between its associated shell and the component already put in place.
