In this work, we focus on the $\\alpha$-decay of heavy isotopes and develop a theoretical description for the $\\theta$-dependence of $\\alpha$-decay half-lives, which enables us to predict the time variation of $\\alpha$-radioactivity in response to an oscillating axion dark matter background. To probe this scenario, we have recently constructed and installed a setup deep underground at the Gran Sasso Laboratory, based on the $\\alpha$-decay of Americium-241.
