Review of recent gamma spectrum unfolding algorithms and their application

Gamma spectrum analysis is regarded as a fast, reliable and non-destructive technology on determining the type and intensity of radionuclides. It is widely used in nuclear physics research, geological exploration, environmental assessment. Under the certain condition (detector, electronic components...
