<p>A process for introducing into a container dry particulate solidifying agent, such as portland cement, and a fluent material, such as a slurry or solution, that is mixable with the solidifying agent to provide ultimately a mass that is at least partially solidified within the container. The solidifying agent which when in a dry condition often has a sizable volume of air contained therein, and a predetermined quantity of the fluent material, are introduced into the container and, after the container is closed, agitated in the container to form a first mixture in which the air is removed from within the solidifying agent. The container is then opened and a second quantity of the fluent material is placed in the container with the first mixture to fill the container to a desired degree. The container is then closed and the first mixture and second quantity of fluent material are agitated to provide a second mixture which is then at least partially solidified in the container. The fluent material is disclosed as radioactive, and two fluent materials of different radioactive intensities may be introduced into the container to produce a solidified mass of a desired radioactive intensity.</p> |
