Bremsstrahlung information for the non-destructive characterization of radioactive waste packages. Final report

The report describes a feasibility study on non-destructive characterization of radioactive waste package using bremsstrahlung information within the gamma spectra. A multi-step was developed for the identification of the bremsstrahlung in the measured gamma spectra under defined boundary conditions. The experimental investigations were performed using a stationary HPGe detector system, a mobile HPGe detector system and a mobile gamma scanner. Further studies are necessary with respect to the possible beta emitting radionuclides in a radioactive waste package.
