Feasibility, system design, and economic evaluation of radiolytic degradation of 2,3,7,8-tetrachlorodibenzo-p-dioxin on soil
Abstract:This research shows that gamma irradiation is both a technically and economically feasible method to degrade chlorinated dioxins on soil. Approximately 99% degradation of dioxin on a model soil was achieved using gamma radiation at a dose of 800 kGy. In addition, this research determined the initial pathway of destruction, identified several controlling parameters, and developed a mass balance on degradation. The general applicability of this model behavior was successfully tested in a native contaminated soil where nearly 75% of the dioxin was destroyed at a dose of 450 kGy. Through a theoretical and conceptual understanding of radiolysis in soil, a sound basis for engineering design was established. Gamma radiation sources are commercially available, and this research outlines a new application of an established technology. A number of irradiator designs are proposed, and preliminary economic estimates are made to demonstrate that radiolysis can be a real alternative to incineration.
