A long-term storage container ( 1 ) for storage of radioactive material to inhibit radioactive radiation therefrom to the outside of the container, the top of said container to be closed by a screw-on radioactive radiation inhibiting lid ( 7 ), said container having an integral inner container part ( 2; 34; 62; 62' ) of a first material, e.g. plastic material, an integral outer container part ( 3; 43; 69 ) of a second material, e.g. plastic material, and radioactive radiation inhibiting material ( 4; 38; 68 ) in an inter-space between the walls and bottoms of said inner and outer container parts. To fill the inter-space an inter-space container part ( 4; 38; 68 ) is integrally moulded through injection or pressure moulding and then fitted onto the inner container part ( 2; 34; 62; 62' ) to subsequently mould the outer container part ( 3; 43; 69 ) onto the outside of the inter-space container part ( 4; 38; 68 ). A specially made container lid ( 7 ) is provided. A preferred twin-mould moulding apparatus ( 61 ) provides for simultaneous pre-casting of the inner container part ( 62' ) and the outer container part ( 69 ) in a respective mould of the apparatus.
