Chemical interface controlled dispersion and high-speed shearing (CDS) washing was conducted for highly radioactive (over 570,000 Bq/kg) contaminated soils from school grounds, moorland and roadsides in Fukushima and the following results were obtained. (1) Washing rate of the three kinds of contaminated soils reached 60-98% a afer 30 min of CDS water washing. (2) Amounts of reclaimed soil (<8,000 Bq/kg) recovered were 60-82 wt%. In the case of moorland soil, 506 Bq/kgx33 wt% was achieved. (3) Volume reductions of 60-85 wt% were achieved for all contaminated soils. (4) Recoverable quantities of total radioactive sources contained in soils were over 90%. (5) The main FP-trapping mineral contained in the contaminated soil of school grounds was lamellar silicate, and that of moorland and roadside soils was mordenite.
