Scintillation spectrometers with mercuric iodide as the photodetector were evaluated for their spectral response to gammas in the energy range of 60 keV to 1332 keV. A /sup 137/Cs (662 keV) photopeak resolution of better than 5% FWHM was obtained due to the low-noise characteristics and high-quantum efficiency of the mercuric iodide photodetector. Photopeak broadening due to the scintillator, electronic noise, and statistical noise versus gamma energy are detailed.
