These radionuclide series are present in slowly decreasing amounts in the environment (geologic time scale), due to radioactive decay of their parents, which has been known and understood since the end of the last century.

Beginning with naturally occurring uranium-238, this series includes the following elements: astatine, bismuth, lead, polonium, protactinium, radium, radon, thallium, and thorium.
The type of decay for each member of the series is shown, as well as the half-lives. Note that some nuclides decay by more than one mode. Name_____ WS Decay Series of U-238 1.

1.1. 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. U-238 and U-235 are the parent nuclides of two independent decay series, while U-234 is a decay product of the U-238 series. Name_____ WS Decay Series of U-238 1.
mass decreases by 32 and atomic number decreases by 11. i will show the 'intermediate steps' doing only one decay at a time. For each decay, the Evaluated Nuclear Structure database (at bnl.gov) has the info, including branching ratios.
