Soil decontamination study, DOE facilities

Research activities related to soil decontamination at Rocky Flats are summarized. The prospect of using soil decontamination methods for decontaminating transuranic (TRU) wastes is good. The approach is to remove the activity by attrition scrubbing followed by dispersion. Significant similarities and differences among soils from 5 DOE sites are discussed. Current guidelines for contaminated soils (actinides) are listed. Criteria for the disposition soil generated in the decontamination process are given. Several decontamination tests are described.
