Abstract
The on-going experiment RadioAxion-$\alpha$, based at the Gran Sasso Laboratory, aims to investigate the time modulation of the $\alpha$-decay of Americium-241 deep underground as a method to explore axion dark matter. We provide the theoretical description of $\alpha$-radioactivity in the presence of an oscillating axion dark matter background and present the prospects of the experiment.
