Statistical learning approaches applied to the calculation of scaling factors for radioactive waste characterization

Abstract : Radiological characterization is needed to dispose of the radioactive waste produced in high energy particle accelerators. We applied statistical learning methods to predict the activity of Difficult-to-Measure radionuclides-which are low-energy X , α-and β-emitters-, to establish criteria for sorting radioactive waste and to quantify prediction errors. Introduction DTM Difficult-to-Measure nuclides cannot be easily quantified by non-destructive assay means. Their activity a DTM is often correlated to the concentration of γ-emitters.
