Energy resolution improvement in simplified alpha spectroscopy for radionuclidic purity tests on 225Ac production floors

Abstract This study investigated the feasibility of a simplified method of alpha spectroscopy for radionuclidic purity tests at 225Ac production sites that eliminates the need for a vacuum chamber. The impact of enhancing the energy resolution using a collimator was evaluated through radiation trans...

Zusammenfassung:	Abstract This study investigated the feasibility of a simplified method of alpha spectroscopy for radionuclidic purity tests at 225Ac production sites that eliminates the need for a vacuum chamber. The impact of enhancing the energy resolution using a collimator was evaluated through radiation transport simulations. The results showed that a full width at tenth maximum (FWTM) of
