Application of a CdTe gamma-ray spectrometer to remote characterization of high-level radioactive waste tanks
Small, shielded cadmium telluride (CdTe) semiconductor gamma-ray detectors have been used for in situ radiological characterization of underground high-level radioactive waste tanks. Remote measurements have been made in gamma radiation fields up to 700 R/h. Spectral data have been used to generate qualitative and quantitative radionuclide profiles of high-level radioactive waste tanks. Two electronic spectral enhancement techniques (pulse risetime discrimination and pulse risetime compensation) have been used in order to measure trace isotopes with photopeak energies greater than 662keV in the presence of large amounts of {sup 137}Cs. Spectral resolution of 1.5% for the {sup 137}Cs 662 keV photopeak has been obtained.
