What Is The Decay Product Of Uranium-238?

What Is The Decay Product Of Uranium-238? The nuclear disintegration of uranium-238 forms radium-226 which disintegrates to form radon gas (radon-222). Radon decays to form a series of daughter nuclides, most of which are alpha-particle-releasing isotopes, such as polonium-210. What does U 235 decay into? Decay of uranium-235 into thorium-231 and an alpha particle. Larger,
