Article Synopsis
- This study explores a new, simpler method for alpha spectroscopy that allows radionuclidic purity tests at 225Ac production sites without needing a vacuum chamber.
- It focuses on improving energy resolution using a collimator, achieving results where alpha particles from 241Am had a full width at tenth maximum (FWTM) of less than 300 keV.
- The method is validated experimentally, effectively separating alpha peaks from different isotopes, and is poised to address the rising demand for targeted radioisotope therapy, particularly in detecting 226Ra mixed with 225Ac.
Cyclotron production of Ac from an electroplated Ra target.

Purpose: We demonstrate cyclotron production of high-quality Ac using an electroplated Ra target.
Methods: Ra was extracted from legacy Ra sources using a chelating resin. Subsequent ion-exchange purification gave pure Ra with a certain amount of carrier Ba.
