For example, uranium-238 (which decays in a series of steps into lead-206) can be used for establishing the age of rocks (and the approximate age of the oldest rocks on earth). Since U-238 has a half-life of 4.5 billion years, it takes that amount of time for half of the original U-238 to decay into Pb-206. (U-238 and U-235), giving rise to one decay series for Th and two for U. To distin-guish the two decay series of U, they were named after long lived members: the uranium-radium series and the actinium seri es. The uranium-radium series includes the most important radium isotope (Ra-226) and the actinium series the most smaller decay series headed by the longer-lived decay products of the original series (that is, headed by uranium-238, uranium-234, thorium-230, radium-226, and lead-210 in the case of uranium-238). Each of these sub-series can be considered to represent a new, separate decay series.

In nature, the radionuclides in these three series are approximately in a state of secular equilibrium, in which the activities of all radionuclides within each series are nearly equal. You will be graphing the dressy series of U-238. You will be graphing the dressy series of U-238. • U-238 and U-235 together with their decay products form aform a “decay chaindecay chain” or “series” the final decay productthe final decay product of which is a stable isotope of lead. • Natural uranium has two decay chains: Actinium series (U-235) Uranium series (U-238) 7 The majority of radionuclides only decay once before becoming stable. Those that decay in more than one step are called series radionuclides.
