Аннотация
This paper presents the application of a full-spectrum analysis method called spectral unmixing for gamma on-board measurements. The method's sensitivity is evaluated through experiments involving various radioactive sources, under challenging conditions such as low signal-to-noise ratios and moving sources. The results are then compared with both an algorithm developed by the CEA/DAM and currently used in operational conditions and the commercial software Genie2000®. Subsequently, spectral unmixing is applied to aerial measurement data. Finally, the study assesses and compares the method's sensitivity and its robustness against false positive alarms with an operational reference algorithm.
