O alpha O … WebFeb 16, 2024 · For example, the decay chain that begins with Uranium-238 culminates in Lead-206, after forming intermediates such as Uranium-234, Thorium-230, Radium-226, and Radon-222. Also called the "decay series.". …
WebRadioactivity - Intro. In nuclear physics, radioactivity is the process by which an unstable atomic nucleus of an isotope undergoes radioactive decay, resulting in either its transformation into a different isotope of the same element (isotope decay) or in the emission of particles such as alpha particles, beta particles, neutrons, or gamma rays.
