Decay characteristics of U-238 series radionuclides There are a substantial number of radioactive isotopes of uranium, including U-234, U-235 and U-238, all three of which occur in the natural environment. However, here the focus is on U-238, which decays via U-234 and Ra-226. Various assessment studies have shown that U-238
Naturally occuring uranium consists of three isotopes: U-238 (more than 99%), U-235, and U-234, all of which are radioactive and have very long half-lives, i.e. decay very slowly.

Another series headed by 235 U contributes very little. Members of the two important series are listed in Table I.Many of the radionuclides in these series decay by emission of alpha particles with energies from 4 to 6 MeV.

29 Jan 2016 Uranium-238 is usually an α emitter (occasionally, it undergoes spontaneous fission), decaying through the “Uranium Series” of nuclear decay,
Radioactive Series A long Radioactive Lineage. From Uranium 238 to Lead 206 This diagram maps the journey on a nucleus map of the uranium 238 decay chain. Decay characteristics of U-238 series radionuclides There are a substantial number of radioactive isotopes of uranium, including U-234, U-235 and U-238, all three of which occur in the natural You will be graphing the dressy series of U-238 Decay Chain of Isotope U-238 The 4n+2 chain of U-238 is commonly called the Radium Series (sometimes Uranium Series). Beginning with naturally occurring uranium-238, this series includes the following elements: astatine, bismuth, lead, polonium, protactinium, radium, radon, thallium and thorium.
