Volatilization of Cesium-137 from Soil with Chloride Amendments during Heating and Vitrification

“…However, under certain environmental restoration conditions, it may be more desirable to volatilize most of the 137Cs leaving a decontaminated glass or residue. The contamination of soil with 137Cs has posed a previously insurmountable challenge for decontamination efforts because the specific fixation of 137Cs by soil minerals makes the resulting contamination extremely difficult to extract or remove (8)(9)(10); aggressive reagents, which dissolve most of the aluminosilicate soil minerals, are generally necessary to remove significant fractions of the 137Cs contamination (11)(12)(13). A recent assessment of the soil contamination with 137Cs following the Chernobyl nuclear accident concluded that soil decontamination was not a feasible alternative (14).…”

“…Cesium is strongly bound to soil and sediment particles and will be transported primarily by particulate transport. For additional information see Spalding and Cerling 1979. Uranium. As evidenced by the development of groundwater-developed uranium deposits, uranium is transportable under certain groundwater conditions.…”
