Genetically related radioactive materials

The equations for growth and decay of genetically related radioactive materials were developed (Bateman 1910) in order to understand the complicated relations among the components of the natural decay chains. Time dependence remains important. First, it is of interest to... 

See O Chap. 7 of Vol. 1 for information on the rates of genetically related radioactive materials and, in particular, the Bateman equations describing members of arbitrarily long chains. Note that each set of equations describes the components of a chain defined for particular branches. Different branches require different set of equations. These points are illustrated in the following sections.
