Isotope packaging container

The invention belongs to the technical field of isotope transporting and storing and particularly relates to an isotope packaging container. According to the technical scheme, the isotope packaging container is provided with an inner barrel and an outer barrel, the outer barrel is made of a stainless steel material, and the inner barrel is made of a depleted uranium material. A two-stage step-shaped inner cavity is formed in the inner barrel. An upper inner cavity body is used for storing a barrel cover, and a lower inner cavity body is used for containing isotope to be transported and stored. A stainless steel barrel lining is installed on the inner wall of the inner barrel. The shape and the size of the barrel lining are matched with the shape and the size of the inner cavity of the inner barrel, and an edge is arranged at the upper end and fixedly connected with the inner wall of the outer barrel. The barrel cover is made of a depleted uranium material and wrapped with a stainless steel cover lining, and boundary dimension of the barrel cover is matched with that of the upper cavity body of the barrel lining. The isotope packaging container has the advantages that after the barrel cover is covered, the shielding layer thicknesses of the periphery of the lower inner cavity body of the inner barrel are equal, while gamma rays are effectively shielded, the weight can be reduced, materials are saved, and transporting is convenient; the stainless steel barrel lining can effectively isolate the isotope and depleted uranium, and cross contamination is avoided; the stainless steel outer barrel and the barrel cover can effectively shield weak radioactivity of the depleted uranium inner barrel, and safety of personnel and environment is ensured.
