Determination of soft X-ray emitting isotopes in radioactive liquid wastes of nuclear power plants
The 59Ni and 55Fe radioisotopes were measured in radioactive wastes of some European nuclear power plants. A sample preparation method was developed that starts with the digestion in an oxygen atmosphere at an overpressure in a closed Berthelot calorimeter bomb. The detection limits for 59Ni and 55Fe were measured and calculated in the presence of high background activities from 60Co, 137Cs and 241Am isotopes.
