Gamma analysis for transuranic waste assay

Passive gamma analysis is one of the key technologies for the identification of transuranic elements in waste material. The techniques use high purity germanium detectors for the detection of the gamma photons. The detected signals are then analyzed in multi-channel gamma spectrometers to determine the photon energies. These photon energies are generally unique to the nuclide that produced the gamma rays and can, therefore, be used as an identifier of the nuclides present. This report is a discussion of methods used to calibrate the measurement systems and for the analysis of the data. 3 tabs
