Analysis of gamma-ray spectra from HPGe detectors in field conditions without explicit energy calibration.
A novel approach to the analysis of high-resolution gamma-ray spectra from HPGe detectors is presented. Identification of the nuclides contributing to the spectrum is performed in an energy-calibration-free manner by a correlation technique. The performance of the system proves to be robust with a possibility of integrating a high degree of expertise. This is most suitable for in-field emergency applications, where intelligent software is of essential importance. The approach is also suitable for laboratory analysis in less experienced laboratories, where HPGe detectors are used sporadically.
