Researchers have developed a novel machine learning approach for identifying radioisotopes in urban environments, converting gamma-ray data into spectrograms for analysis by computer vision architectures. This method encodes both spectral and temporal information, enhancing the ability of neural networks to distinguish threat signatures from background noise. Evaluations on the RADAI benchmark dataset showed that a convolutional neural network (CNN) outperformed previous methods, achieving higher detection, classification, and identification rates at a low false positive rate.
