Abstract
The detector characteristics of CZT and NaI spectrometers that affect the choice of the nuclide analysis algorithm were analyzed with a general purpose Monte Carlo code to simulate the SNM spectra. The physical and geometric conditions strictly adhered to the IAEA series test requirements for a portable radionuclide identification device. The Hecht equation was used to describe the incompletion charge collection effect for the CZT detector, and a comparison calibration to determine the CZT spectrometer equivalent noise charge. The NaI spectrometer was calibrated by experiments. The calculated results agreed well with experiments.
