Gasses containing carbon monoxide and hydrogen are converted into hydrocarbons using a reactor vessel having a liquid, a catalyst dispersed in the liquid, and a sonic mixing system interfaced with the reactor vessel. The sonic mixing system is used to agitate the mixture. In combination with the catalysts, the agitation increases reaction kinetics, thereby promoting chemical reactions used to efficiently convert gasses containing carbon monoxide and hydrogen into hydrocarbons.

A composition for use as a radiation shield. The shield is a concrete product containing a stable uranium aggregate for attenuating gamma rays and a neutron absorbing component, the uranium aggregate and neutron absorbing component being present in the concrete product in sufficient amounts to provide a concrete having a density between about 4 and about 15 grams/cm.sup.3 and which will at a predetermined thickness, attenuate gamma rays and absorb neutrons from a radioactive material of projected gamma ray and neutron emissions over a determined time period. The composition is preferably in the form of a container for storing radioactive materials that emit gamma rays and neutrons. The concrete container preferably comprises a metal liner and/or a metal outer shell. The resulting radiation shielding container has the potential of being structurally sound, stable over a long period of time, and, if desired, readily mobile.

An in situ waste treatment system for contaminated soil employs a high temperature energy probe which is lowered into a borehole casing that has been inserted into the contaminated soil. The energy probe is activated and then melts surrounding region of the contaminated soil. The probe is raised and continues to melt a cylindrical column of soil that surrounds the borehole casing. Oxygen is introduced into the molten material so that organic and metallic components thereof are oxidized. In basaltic soils superheating and nucleation materials are introduced to enhance formation of a crystalline structure in the contaminated soil as it solidifies. Increased crystallinity makes the resultant solidified basaltic materials more resistant to leaching by ground water. Other types of contaminated soils are treated with waste modifiers to produce optimum leach resistance of the resultant resolidified soil.
