Summary

This work investigates radioisotope identification with gamma ray spectroscopy using three detector types—NaI(Tl), CZT, and HPGe—for the characterization of both simple and complex irradiated materials. Instead of traditional peak-based nuclide identification, Machine Learning (ML) classification algorithms are employed to enable faster and more robust isotope recognition. Training models on simplified spectra enhances classification accuracy when applied to complex mixtures.
