Section: claims

1. A container for the storage and transportation and radioactive material comprising: an elongated vessel receiving said material and having a wall thickness and composition attenuating radioactive transmission therefrom, said vessel having an open end formed with an annular thickened portion defining a mouth communicating with the interior of said vessel;  a radiation-shielding cover received in said mouth and having a plug-forming portion juxtaposed with a complementary seat-forming portion of said vessel at said mouth, and a flange extending outwardly from said plug-forming portion, said vessel being provided with a wall bore communicating at one end with the interior of said vessel and open at its opposite end, said radiation-shielding cover extending outwardly beyond said wall bore, said radiation-shielding cover being provided with a connecting bore registering with said wall bore;  an obturating element received in said connecting bore and adapted to block said wall bore;  a further cover secured directly to said vessel outwardly of said radiation-shielding cover and overlying said wall bore and said radiation-shielding cover, said radiation-shielding cover being formed with at least one control bore in the region of said seat-forming portion and covered by said further cover, said further cover defining with said radiation-shielding cover a control compartment into which said control bore and said connecting bore open and provided with means whereby the sealing effectiveness of said radiation-shielding cover can be monitored; said vessel being provided with a recess, said further cover being received in said recess against a shoulder formed by said vessel outwardly of said radiation-shielding cover; and  another cover lying outwardly of said further cover and at least partly received in said recess. 2. The container defined in claim 1 wherein said other cover defines a second control compartment with said further cover whereby leakage from the interior of said vessel can be monitored. 3. The container defined in claim 1 wherein a control cover is secured to said vessel above said other cover and defines a second control compartment therewith whereby leakage from the interior of said vessel can be monitored. 4. The container defined in claim 1, claim 2 or claim 3 wherein said wall bore opens at said other end at said seat-forming portion.
