A multi-radionuclide energy spectrum of Co-57 (122 keV and 136 keV), Tc-99m (140 keV), I-123 (159 keV) and In-111 (171 keV and 245 keV) acquired with the HPGe detector. The energy resolution of our HPGe detector provides sharp and distinguishable photopeaks, which makes it ideal for nuclear imaging using multiple radionuclides.
