ANNOTATION:

Nuclide-vector method (scaling-factor method) is used to determine the radiation characteristics of radioactive waste based on the identified dependences between the contents of difficult-to measure radionuclides (239Pu, 241Am) and key radionuclides (60Co, 137Cs, 152Eu, 154Eu). The application of this method allowed to reduce the number of sampling operations and advanced radiochemical analyzes of radioactive waste during its categorization, to reduce the radiation impact on personnel, the total time and cost of operations performed during waste characterization. The paper describes the application of the nuclide-vector method enabling to identify the radiation characteristics of a large amount of radioactive waste with complex composition, containing difficult-to-measure radionuclides along with relevant demonstration of its effectiveness.

Keywords: radioactive waste, nuclide-vector method, difficult-to-measure radionuclide, confidence interval.
