Abstract

A set of 100 gamma-ray spectra with known traces of anthropogenic nuclides was utilized in the First System-Wide Performance Test (SPT1) of the Comprehensive Nuclear-Test-Ban Treaty Organization (CTBTO) in June 2005. The spectrum set was very realistic, since it is based on real measured spectra. Yet, the correct spectrum contents are known, when anthropogenic peaks with known areas have been synthesized into the spectra. This paper investigates the key performance indicators for the UniSampo-Shaman software package when applied to these spectra, concentrating on results from automated pipeline analysis. In summary, the UniSampo-Shaman performance is very satisfactory and fully in line with previous evaluations.
