ABSTRACT:
A method for manufacturing a long-term storage container for storage of radioactive material to inhibit radioactive radiation therefrom, said container having a bottom and upright wall extending therefrom, the top of said container to be closed by a screw-on radioactive radiation inhibiting lid, said container having an integral inner container part of plastic material with a bottom and upright wall, an integral outer container part of plastic material with a bottom and upright wall, and radioactive radiation inhibiting material 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 is integrally molded through injection or pressure molding and then fitted to either the inner container part to subsequently mold the outer container part, or fitted inside the outer container part to subsequently mold the inner container part.
