Web9 de abr. de 2024 · Radioactivity is a nuclear property, as proposed by Rutherford and Soddy (1903). A radioactive atom has an unstable nucleus. It disintegrates or decays through the spontaneous emission of α- or β-particle. The proton-neutron ratio of neutron shifts as a result, creating a more stable atomic structure.
