Abstract

Method and apparatus for encapsulating radioactive plastic wastes, particularly radioactively contaminated ion exchange filter material containing water, in bituminous solidification substances, by drying the radioactive waste separate and apart from the bituminous substance, introducing regulated amounts of dry radioactive waste into the bituminous substance and kneading the mixture at a temperature of 120.degree. C. or lower to encapsulate the dry radioactive waste by the mechanical action of the kneading, and pouring the kneaded, encapsulated radioactive plastic waste into a container. Undesired decomposition with discharge of pollutants into the atmosphere are avoided.
