FIELD: recovery of liquid radioactive waste.
SUBSTANCE: proposed method for recovering liquid radioactive waste of low level of activity from 137C radionuclides by extracting 137C radionuclide and alpha-ray nuclides involves introduction of magnetite slurry into solution being decontaminated, settling down of ferrocyanide magnetite particles selective to metal cesium extraction due to introduction of potassium ferrocyanide and soluble salt of respective metal into solution, and correction of solution pH to 9 by means of alkali. Sorbent is removed by settling it down followed by additional decontamination of cleared solution using magnetic separation method.
EFFECT: ability of decontaminating low-activity liquid radioactive waste from cesium radionuclides and alpha-ray nuclides.
