摘要：<p>The invention relates to packaging for transporting radioactive material (1), including a radiation protection structure (4) comprising a shielding portion (5) defining a cavity (2) for receiving the radioactive material and a portion (7) that has the effect of distancing the radioactive material from the outside of the packaging. The distancing-effect portion (7) directly encloses the shielding portion (5). The protection structure (4) has a thickness e associated with a segment (S) connecting a point (B) on the outer surface of the packaging to the center of gravity (G) of the cavity (2). Said thickness satisfies, for any point (B): e=e1+e2 and 0.05<e1/e<0.25, where e1 is the thickness of the shielding portion (5), e2 is the thickness of the distancing-effect portion (7), and e1 and e2 are associated with the segment (S). The shielding portion (5) has a mean density of more than 8, and the distancing-effect portion has a mean density of less than 0.5.</p>
